This tetra makes an ideal aquarium fish, but note a few factors that will help enhance this beautiful fish. It is not one of the smaller popular tetras and can grow to just over 6.5cm, making it a medium-sized fish. In the wild they feed and breed in large shoals, so it is best to keep them in groups og 6 or more.
Size: 3 cm
Red Blue Columbian Tetra are very active swimmers with large eyes and a good set of teeth — all indicators of a fish good at catching its prey and capable of avoiding being eaten by larger fish. On the rarest of occassions they may chase other tank mates and nip their fins, but this is rare. You should still avoid mixing with slower moving fish with flowing fins such as fancy guppies and try to select fish of their own size.
