Care caveats

notesSmall peaceful rainbowfish; calm, shimmering schooler that rewards patient planted setups.
caveatKeep a group of 6 or more; in smaller groups celebes rainbows hide and lose color.
caveatAdd only to a cycled, mature tank with steady tropical parameters; the species does not handle ammonia/nitrite swings well.
caveatEasily outcompeted at feeding by aggressive or boisterous tankmates — pair only with calm community species, not large barbs or rough cichlids.
caveatBest in planted community tanks with open swimming length between plant groups; small, sparse setups stress them.
