Part of the aquarium hobby experience is screwing stuff up.
There are so many things that we do as aquarists which involve variables beyond our control, that failure in some things is almost inevitable.
And, after a lifetime in the hobby, I will occasionally reflect back on some of the great successes that I’ve had...and on some of the many, many failures that I’ve been involved with! Failures aren’t that bad, really. In fact, they're pretty damn helpful...As the sayings goes, “Nothing is ever wasted- it can always serve as an example of what NOT to do!”
Yeah, because if you learn from them, failures or disasters are extremely valuable tools for self-education.
I was thinking about my worst-ever aquarium disasters, and, fortunately, there have not been all that many...However, the ones I have had have been notable...and very educational!
My biggest mistakes came out of my own arrogance, really. Yes, arrogance. A desire to flaunt the "rules" set by Nature.
Usually, they were "created" when I tried to do something that disregarded simple logic (and a century of aquarium common sense), like trying mixes of fishes that were absurd, or overstocking tanks...stuff like that.
For example, from my reef keeping experience- not all that many years ago, actually- I was going to be the ONE reefer to keep several Centropyge angelfish in his reef, including a Lemonpeel, Vrolicki, Coral Beauty, Flame Angel, and Bicolor! If you don't know anything about the dwarf angelfish of the genus Centropyge, the one thing you SHOULD know is that they are very territorial, and don't generally get along with others of their own species. And mixing different species is a traditional "recipe" for disaster.
Oh, and most of the ones I wanted to keep had a well-earned reputation for snacking on coral tissue...What could go wrong here?
This was a recipe for failure that even the most inexperienced reefer could see coming. Of course, I was "experienced", so I knew better, right?
Nonetheless, I really thought I could pull this off in a large reef with specialized aquascaping... I was convinced that it could work and that I'd be the envy of the reef aquarium world for doing so...Not only did this experiment end with some "predictable" results (a lot of nice corals getting snacked on), it resulted in 5 very ticked-off, very beaten up dwarf angels! No shit? Who would have seen that coming, right?
Just plain stupid...For some reason, I really thought that my “methodology” would pay off and that it could work...WRONG.
But hey. I did it. I failed at it. I OWN it.
I distinctly remember a dubious experiment on the side of my parents' house one summer when I was a teen, attempting to culture mosquito larvae...yeah, you know how well THAT went down! I think that was the most mosquito bites I've ever had in one summer...
But I learned my lesson....
Or the time I tried to build my own fluidized reactor. It sounded like noble project, but the reality was that I started with a bad concept and used cheap PVC materials that didn't quite match up. Yeah, it didn’t work, and the resulting leaks and total lack of functionality reflected my DIY "skills!" It was a good thought, but really poor on the "execution" side.
Completely unlike the Angelfish fiasco, which was a “lose-lose” proposition! Nowadays, if I have the urge to do DIY, I simply break out the credit card and purchase whatever it is I was thinking of making. Aquarium equipment manufacturers LOVE me!
Another lesson learned.
Oh, or there was that time I tried to make a continuous-feed brine shrimp hatcher...Shit, do you know how LONG it takes to get brine shrimp eggs out of the water column in your tank?
A really long time.
However, failing- and I mean this in the most literal sense- can actually be beneficial in so many ways, especially if you share your failures publicly. Right now, somewhere out in the aquarium hobby world, there is another hobbyist contemplating one of the same absurd, disaster-inevitable ideas that you brought to life...
Perhaps it's not some huge, epic-disaster-bound system failure...Maybe, it's just something that's a bad decision; one that should be aborted on, but isn't likely to be- and the outcome is already well known in the hobby...
Maybe it's in our nature as hobbyists; we just love to tempt fate. And look, I get it...I've written on these very pages that sometimes, we need to go against the grain and try new ideas.
Even after 6 years of pushing this idea of botanical-style aquariums, we're still learning some new ideas, creating "best practices", and evolving techniques. We still make a few mistakes. And, like many hobbyists, we're still trying to get our heads around the "big picture" of the approach, which seems so contradictory to what has been passed down as "the way to do stuff" in the hobby for generations.
It makes many people uncomfortable to take leaps of faith. And, sure, despite the successful implementation of these techniques for several years by thousands of hobbyists, there is always a chance of failure.
It's scary. It can be viewed as "irresponsible" by some. At the very least, you might question the efficacy and safety of some of this stuff.
It makes sense.
We ask you to make a lot of mental shifts accept some ideas which seem to go "against the grain" of long-held hobby "best practices" and philosophies of aquarium management.
We ask you to understand what you are doing what you are doing, and what the rationale behind the approach is.
One thing that you do get when ideas are shared like this is the benefit of the body of work; the experience- good and bad- of a large community of hobbyists who have went down this same path. The key to taking an idea from "fringe" to "best practice" is sharing.
Sharing of mistakes made, the refinements done, and the "tweaks" that yielded consistent success.
It starts by creating a hobby culture of sharing.
Sharing of our mistakes is every bit as important as sharing our amazing successes.
So imagine, for a moment, if you do a quick “confessional” post on Instagram or Facebook about your biggest aquarium screw up, and just one hobbyist who is contemplating a similar thing stumbles on it, and then decides NOT to recreate your disaster!
Think of the savings in money, frustration, and innocent animals’ lives...It’s all good. "Failure" makes you a more successful aquarist- IF you learn from the mistake, and IF you share it with others!
It's kind of fun, too!
So, don’t hide your failures.
Trumpet them from the highest mountain. Savor them. Run around, scream, share, yell at people if you must...But tell ‘em that you screwed something up...Tell them how, why, and what it was that you did to screw it up!
Then laugh about it and feel better! Look at the absurdity of the thing you did.
Of course, some seemingly counter-intuitive ideas do work.
Sometimes, you try something that YOU think will be a mess, but your friends know will work, because they've done it many times, and have refined the idea and practices. You're a bit scared...and you do it anyways based on their ideas! And it DOES work! Like recently, when my friend convinced me to try several male Apistos of different species in my display tank...I was like, "Dude...really?"
And he said, "Trust me." And I did. And it was awesome!
Think about "failure" in the context of the bigger picture...
The neat thing about mistakes, screw-ups, and "failures" is that they often lead to something far, far better than whatever it was that you initially failed at. Because, if you take the time to ask yourself why it happened, and reconstruct the process, and make necessary adjustments and recalibration, you'll often find that the idea can work- just in a slightly different manner than you originally thought.
And failures are only failures if you don't learn from them.
Even in our business, we screw up shit all the time, and usually it's our own fault. And we try to learn from them and refine our processes to make sure that they don't happen again.
In fact, I've been working on a piece on the many screw-ups we’ve made here at Tannin. It’s actually kind of funny, because there ARE so many!
"Marketing blasphemy", you say? No. Not at all. Rather, it’s a living embodiment of practicing what we preach...
As humans, we all make bad decisions from time to time. Some are the result of pushing boundaries...others are simply bad judgement. Again, how the mistake was made isn't quite as important as learning from it is.
We will all benefit from being human, being honest, and getting through our trials and tribulations in fish keeping together. And yeah, we all have more to gain than to lose from sharing our mistakes.
What’s the biggest screwup- the worst mistake- that you’ve made in aquarium keeping? What did you learn from it?
Don’t be shy. Own it. Share it. Your "failure" will likely lead to others succeeding...So, it wasn’t really a failure after all, right?
Stay bold. Stay thoughtful. Stay honest. Stay curious. Stay experimental...
And Stay Wet.
No brackish water aquarium is complete without brackish-water fishes...And traditionally, that has been a bit of a challenge, in terms of finding some "different" fishes than we've previously associated with brackish aquariums. I think that this will continue to be a bit of a challenge, because some of the fishes that we want are still elusive in the hobby.
New brackish-water fishes will become more readily available when the market demand is there. In the mean time, we can focus on some of the cool fishes from these habitats which are currently available to us.
And there are a few!
They can be hard to find; however, I think the biggest challenge facing those of us who love brackish water aquariums is trying to separate aquarium "fact" from scientific fact! This is pretty fun to do, actually.
However, one of the things I've found is that you need to go beyond "what the hobby articles say" and look into actual information from scientific sources about the types of habitats our target fishes actually come from. There is still a surprisingly large amount of misinformation about there concerning fishes long thought to be "brackish", when the reality is that they are often found predominantly in non-brackish habitats, with perhaps only isolated populations of them being brackish fishes.
Like many hobbyists who play with brackish water tanks, I've found over the years that it's mighty tricky to source genuine brackish water fishes. Through lots of follow up and a bit of luck, I have managed to secure fishes from these types of habitats from time to time, which is, of course, paramount if you're trying to recreate one of these habitats in your aquarium!
As most of you know, I'm no huge cichlid fanatic, but there are some which have found their way into my heart over the decades. One of these is a genuine hobby legend, which just happens to be one of my fave all-time fishes: The venerable "Orange Chromide", Pseudetroplus maculatus - a cichlid with a very weird popular name.
Despite being a cichlid (😆), the Orange Chromide is a relatively easy-going fish that tops out at about 4" in size, which is a huge plus in my book. And, being one of the very few species of cichlids which comes from India, it's even more interesting. In fact, there are just three species which are native to India: Etroplus suratensis, Pseudetroplus maculatus, and the cool and hard-to-find Etroplus canarensis.
Oh, the name. It drives me crazy:
The official Meriam-Webster origin of the name is, "chromide, ultimately from Greek chromis, a sea fish"
A sea fish? WTF?
Yeah, not really satisfying. And it begged me to do little more digging, of course!
But I tried to find out more for you. Now, interestingly, the fish was originally described by the ichthyologist Bloch in 1795 as Chaetodon maculatus...and if this genus sounds familiar to us saltwater aquarium geeks, it should- that's the same genus in which many marine Butterflyfishes are found. And, the fish seems to bear at least a very superficial physical resemblance to a marine Butterflyfish of that genus at first glance...
So, the "Chromide" part of the popular name refers to it's appearance as a "sea fish", or chromis. And, to add a final note of confusion to this taxonomic/popular name scramble, Chromis is a popular genus of colorful marine Damselfishes... So the popular name of this fish is based on it being confusingly similar in appearance to a marine fish... Oh, weird, right?
Yeah, that's why common names are often fraught with problems, and for the ultimate in accuracy, we should at least have a working familiarity with the Latin species names of our fishes. Oh, and this little fish has been bounced around a few genera over the years, from Chaetodon to Etroplus, and finally to Pseudetroplus!
Okay, whatever you call it...This is a pretty interesting fish! Even if it IS a cichlid!😆
And, about that brackish-water thing...
The Orange Chromide endemic to freshwater and brackish streams, lagoons and estuaries in southern India and Sri Lanka. And of course, as soon as we in the hobby hear the word "brackish" when discussing some of the natural habitats in which the fish is found, it forever becomes a brackish water fish!
That's just how it goes in the aquarium hobby, right?
The reality is that the Orange Chromide is classified as a euryhaline fish, and mostly inhabits brackish estuaries, coastal lagoons and the lower reaches of rivers.
Damn, we've heard that term before, haven't we?
That single definition seems to give us as hobbyists the freedom to label the fish as a brackish water fish, despite the fact that it has the ability to live in both pure freshwater and brackish water conditions.
It helps to know exactly where your specimens come from, right?
I was lucky when I sourced my specimens, as there was no ambiguity about what type of habitat they were originally from. Or should I say, where their parents came from. They were actually F1 from parents collected in a brackish water lagoon in the state of Karnataka in western India, so I was pretty happy to be able to keep them in a brackish aquarium and have the confirmation that they were only a generation removed from a natural brackish water habitat.
Okay, all well and good for me, but what if you're not so sure about where your Chromides come from? Well, as we discussed a minute ago, they are euryhaline fishes, and can adapt to brackish relatively easily. You just need to do it very gradually, like over a week or more.
Now, one thing I will tell you about these fishes is that, despite their peaceful reputation, and relatively they can be little shits among themselves. These guys are pretty social...but they also have a social order, which is maintained when feeding and even schooling. The "Alpha male" generally gets to eat first, followed by the less dominant specimens..and of course, he leads the "pack" when they school in the tank (and they do, which is pretty cool!).
And, yeah, the social order in a group of these guys is a big deal. The dominant fish WILL, indeed pick on the weakest ones. In fact, I lost a few over the years due to a super aggressive dominant male essentially bullying and beating the shit out of the subordinate ones in my group before I could remove them.
However, I will tell you to keep them in a group. Not only do they seem to be happier that way, but they display the most interesting behaviors- short of this harassment of the really weak ones. I'd love to tell you that, with a large enough tank, this won't be as big an issue, but I kept mine in a decent-sized tank with lots of hiding spaces and it still was an issue, so...
Another thing about these fishes that you will read is that they are relatively intolerant of poor water quality. Without sounding like an arrogant S.O.B., I'd have to tell you that I won't dispute this, but can't confirm it, because- like most of you- I maintain high water quality in my tanks! It's one of those things that I will just typically accept as a given.
Like many cichlids, spawning is typically a given, given the passage of time and under appropriate environmental conditions. (ie; being in water...)
In the wild, the Orange Chromide spawns in shallow water, typically in a depression in the substrate excavated by both parents. What that tells you, BTW, is that this fish is best kept in a tank with sand, sediment, or other soft substrate materials if you intend to breed them.
It's time to play with dirt, soil, mud, silt, decomposing leaves, branches, marginal plants, roots...materials which replicate both the appearance and function of natural habitats from which many of our fishes come. And, if utilized skillfully and thoughtfully, can yield functionally aesthetic aquariums far different and unique from anything previously attempted in the aquarium hobby. Another call to the evolved, botanical-style brackish-water aquarium!
In Nature, Orange Chromides spawn twice a year, during the drier pre-monsoonal and monsoonal seasons, in which the salinity is slightly higher (an interesting takeaway for us!). During these times, the turbidity of the water is lower, and the parents can more easily construct their nests and maintain visual contact with their fry after they hatch.
Interestingly, in Nature, when Orange Chromide pairs spawn in isolation, they tend to construct nests in areas of dense aquatic vegetation or root systems, which provide a lot of camouflage. Ecologists also have noted that during the month of July, which is their peak breeding season, Chromides will construct their nests in areas that are rather sparsely filled with vegetation, roots, etc.- a sort of compromise between fry survival and foraging opportunities for the adults.
Other, non-spawning fishes will also make use of these areas, increasing the threat to the broods of fry which emerge after hatching. Under these conditions, most Orange Chromides nest in colonies, which is believed to help decrease predation.
Hmm, breeding colonies? Interesting!
About 200 eggs are laid in a typical event, according to just about every source you'll find in the aquarium world. Of course, the largest batch I ever counted was around 100 or so eggs. The eggs hatch after about 5 days, during which time the parents tend to, and fan them.
In typical cichlid fashion, one parent will always remain with the eggs while the other goes out and forages for food. The fry of Orange Chromides feed on the mucus secreted onto the skin of their parents, like Discus or Uaru do. This form of feeding is called "contacting" by biologists. And perhaps most interesting, the good-sized fry are guarded by parents until they almost reach sexual maturity and are almost the size of the parents! Like, a pretty long time! This is a very unique behavior in cichlids!
It is known that immunoglobulin concentrations are higher in the breeding fish than they are in non-breeding ones, and are highest in wild breeding individuals. Biologists are curious to ascertain whether this immunoglobulin is passed on to the contacting fry in the same concentrations as it is found in the mucus. If it is, the big question is how does the increased amount of immunoglobulin affect the growth and survival of these fry?
Want a final bit of unusual trivia on this fish?
Yeah, it's been documented by researchers Richard L. Wyman and Jack A. Ward that the young of Pseudetroplus maculatus actively clean the related species, Etroplus suratensis (the "Green Chromide") when they occur together. .E. suratensis are naturally inhibited from attacking small fish, in case you are wondering!
Much like what you see in the ocean, with Wrasses or Shrimp cleaning territories are established by the young Orange Chromides, and the "shop hours"seem to follow a daily circadian rhythm. This is a unique, almost symbiotic kind of behavior, in which removal of fungus from fins and tail of the E. suratensis appears to be an important adaptive function of this symbiosis.
Interestingly, it's thought by researchers that the "contact feeding" behavior in Orange Chromide fry during parental care may have aided in the evolution of this cleaning relationship. This represents the first report of a cleaning symbiosis involving cichlid fish.
So, yeah, there is much more to this "old hobby favorite" than we might first imagine!
So, what would be some cool ways to keep this fish? Well, to begin with, you should definitely keep them in an aquarium with a fair amount of substrate, roots, and perhaps even a few aquatic plants. Now, if you're aiming to go brackish, it brings up the usual "What plants can grow in brackish water?" discussions...And yeah, there are a few, and you'll need to research that. (Hint: Cryptocoryne ciliata )
Or, you could keep it simple and go for something like a tangled hardscape, with wood and roots, mixed with sand and small quantities of rubble. This would be a very interesting representation of the monsoonal conditions.
Or, you could simply do a "proper" brackish water aquarium with my fave all time plant, the Red Mangrove (Rhizophora mangle). This would be a very rewarding way to keep these fishes, as I can attest!
Yes, new brackish-water fishes will become more readily available when the market demand is there. In the mean time, we can focus on some of the cool fishes from these habitats which are currently available to us, like our pal the Orange Chromide. And the brackish water habitats are as interesting, dynamic, and bountiful as any on the planet.
There is still a surprisingly large amount of misinformation about there concerning fishes long thought to be "brackish", when the reality is that they are often found predominantly in non-brackish habitats, with perhaps only isolated populations of fishes being brackish fishes.
Fortunately for us, our friend the Orange Chromide is one of those which you can do the research on and find a surprisingly large amount of interesting, scholarly information out there.
You just have to be willing to look.
Stay motivated. Stay curious. Stay excited. Stay diligent. Stay persistent...
And Stay Wet.
