Here is a cool botanical that is a bit of an oddball , actually.
When dried, it has shiny, leathery "skin" and a firm "woody" interior. After you boil and/or soak it, the interior softens considerably. The interior of pod breaks down relatively quickly- in as little as 2-3 weeks. This is not necessarily a bad thing, mind you- but it does start to decompose and recruit a biofilm quite soon after introduction to water. Shrimp apparently really like to feed on the biofilm, and as the interior starts to go- the pod itself. Plecos seem to like rasping on the soft interior of the pods, which makes us think that these might be kind of good as an occasional "treat"- sort of the piscine equivalent of a "chew toy", if you will.
They are aesthetically quite attractive, especially the shiny outer segment...but they are not what we'd call "long duration" botanicals, due to the relatively quick breakdown of the interior. On the other hand, once the interior is essentially gone, you have this amazing outer "skin" that looks so cool and lasts indefinitely! So our recommendation is to experiment with these. Add them to your tank a couple at a time, and see for yourself how the inhabitants utilize them! And of course, enjoy the outer skin for its beauty.
Another great pod to mix in with your leaf litter. They are clean, free of pesticides or other contaminants, and are carefully collected and sun dried.
"Couro Casca Curls" are another "lightweight" botanical, which are essentially like heavier leaves in their texture, appearance, and use. Another perfect aquatic botanical to simulate the tropical stream biotope, providing foraging areas for fish like Tetras, Dwarf Cichlids, and catfishes. They vary widely in size, ranging from about 1.5"-2.5" in length, and around 1"-1.25" wide on average.
These pods will leach some tannins into the water over the long term. You'll need to prepare them in order to waterlog them, because they float like crazy when first immersed! You can boil them for at least an hour, followed by a 1-2 day soak in freshwater, before use.
"Couro Casca Curls" are unique aquatic botanicals, and they offer a great combination of aesthetics, form, and function for aquarium use! We offer them in a package of 8 pieces, to give you multiple aesthetic and utilitarian options.
NOTE: These are a natural product, and display variation in color, size, and texture. Each pod is unique! The photo serves as a reasonable representation of what to expect.
All of our aquatic botanicals are intended for ornamental aquarium or terrarium use only. Please use common sense and take the time to boil or soak all botanicals prior to using them, to reduce the possibility of problems. Always go slow when introducing any botanicals into your systems, so you can judge the effect they have on your fishes and plants. They are not intended for human consumption. DO NOT INGEST!
