It's funny that this very pleasant-looking fish has been given the rather undignified common name, "Least Rasbora"- as if to imply that it's somehow unworthy of the family- which couldn't be further from the truth! It's a really fantastic fish for the peaceful, Asian-themed community aquarium.
Hailing from swamps in Southern Thailand, these fish are adaptable to a variety of environmental conditions. They are found in clearwater and blackwater habitats, and are even known to inhabit areas which are temporarily inundated during the rainy season.
Although it's a small (approx 0.5"-0.75"), rather delicate-looking fish, it's surprisingly hardy, and can adapt to acidic to slightly alkaline aquarium conditions (like in the 6.6-7.2 range). It's an ideal fish for botanical-style aquariums, clear or blackwater style. They tend to be a bit light-shy, so some shade from floating plants or overhanging wood is appreciated.
Although they don't need a large aquarium, physical space is important, as it will provide them enough space to engage in their natural schooling behaviors, and to engage in courtship rituals. Maintaining them in a group of at least 8 specimens seems to encourage all of this entertaining behavior, so that's how we offer them! If your aquarium and budget can accommodate more than 8 specimens, we say go for it! Although perfect for a dedicated species aquarium, they may be kept with other small, peaceful fishes which come from similar environmental conditions, such as small Gouramis, wild Bettas,
Being micropredators, they'll consume a variety of small crustaceans, such as Daphnia, baby Brine Shrimp, and fruit flies will be perfect for them. You can adapt them to eat prepared foods, like flakes and pellets, once they've acclimated to aquarium life.
All-in-all, these diminutive, colorful fish are perfect for small, "feature" aquariums. Our specimens are well-fed, nicely-adjusted fish that will acclimate readily if provided their preferred conditions.
Fun fact: The genus name, "Boraras" is actually an anagram of the genus Rasbora, which the fish is related to, yet has a reversed ratio of caudal and abdominal vertebrae-hence the name! Neat stuff, huh? Yeah, we thought so.
