Care caveats
- notesTiny, peaceful nano-schooler; needs mature water and quiet planted tanks to settle and color up.
- caveatKeep a group of 8 or more; small groups hide and lose color.
- caveatVery small adult size makes them vulnerable to larger tankmates — many community fish will eat or harass them.
- caveatBest in mature, planted nano or community tanks with steady parameters; sensitive to ammonia, nitrite, and parameter swings.
- caveatPair only with calm, similarly sized tankmates (other small rasboras, pygmy corys, shrimp); avoid boisterous or predatory species.
