In the aquarium
Costello tetras have been kept in the aquarium hobby. Some foods aquarists feed them include flakes, pellets, and live foods. Wild caught specimens sport a characteristic golden sheen to their scales, this is due to the presence of a parasite found within their native range that causes the unusual pigmentation, captive bred Costello tetra do not display this coloration, and instead present with a silver iridescent scalation, more typical of many others within the Characidae family.
