Undemanding and non-aggressive. Good tankmates include similarly-sized Australasian rainbowfishes, barbs, characids, peaceful cichlids and catfishes. In a Madagascan community it can be used as a dither for endemic cichlids such as Paratilapia polleni, Paretroplus menarambo, Ptychochromis oligoacanthus, etc. It’s best to avoid keeping it with other Bedotia spp. as there is a possibility of hybridisation taking place.
It’s a schooling species by nature and really should be kept in a group of at least 8-10 specimens. Maintaining it in decent numbers will not only make the fish less nervous but will result in a more effective, natural-looking display. Males will also display their best colours as they compete with one other for female attention.
