A resident of the blackwater streams and swamps of Southern Peninsular Thailand, the Three Spot Dwarf Rasbora, also known simply as the "Dwarf Rasbora", is a little gem that's a perfect resident for a blackwater, botanical-style aquarium! The streams and peat swamps from which the fish are native feature darkly-tinted water filled with leaves and other botanical materials, and have very soft, acidic (as low as 4.0ph!) water.
These are really hardy fish, and are perfect for a biotope aquarium featuring Gouramis and other peaceful small Cyprinids from the region. It goes without saying that we're fond of keeping them in blackwater systems, and we're pretty confident that the humic substances produced by leaves and other botanical materials are of a definite health benefit to the fish.
Lighting need not be bright, and the aquarium should be well-established, and ideally, chemically and biologically stable, without significant fluctuations in environmental parameters. We like to keep them at temperatures around 77-78 degrees Fahrenheit. Maintaining them in a group of at least 10 specimens seems to encourage more comfortable natural behaviors, so that's how we offer them!
Being micropredators, these little guys will eat a variety of small crustaceans, so food like 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.
