Overview
The largescale rasbora is a small, peaceful schooling fish for a planted community tank. A moving group catches the light off its scales like flecks of beaten metal. It is best with a little experience.
Did you know
Each scale along the largescale rasbora's flank is large enough to pick out by eye. Together the plates tile the fish in visibly coarse mail.
Caring for the largescale rasbora
Give a group of largescale rasboras a planted tank of 20 gal (75 L) or larger, with open lanes. A dark substrate, gentle to moderate flow, and some leaf litter or wood to tint and soften the water suit them.
Keep the water soft and on the acidic side, at 72 to 81°F (22 to 27°C) and a pH of 5.5 to 7.0. Feed small foods they can handle, such as crushed flake and micro pellets, with frozen daphnia, cyclops and baby brine shrimp.
Keep a school of eight or more. They are peaceful and stay in the middle of the tank, so a calm community of similar-sized, gentle fish suits them. Their breeding remains undocumented in aquaria.
Good to know
Rasbora paucisqualis is a rasbora in the danio family, Danionidae. Ahl described it in 1935, and the name means few-scaled. Its scales are noticeably larger, and therefore fewer, than those of most rasboras.
In the wild
The largescale rasbora lives in clear, swift forest streams and pools from the Mekong basin south into Malaysia, in soft, slightly acidic water.
