Cochus Blue Tetra

Blue tetras are schooling fish, meaning that they rather live in groups. Keep the blue tetra in a group of six or more fish.

Although generally quiet and peaceful, the blue tetra does have a slightly aggressive streak, especially towards other fish species and when there isn’t enough space in the tank to swim freely.
