RED EYE PUFFER (Carinotetraodon irrubesco) D2405M

Less aggressive than some members of the genus but nevertheless best maintained alone or alongside a group of peaceful, schooling cyprinids of a size large enough to escape predation but small enough that they offer no competition or threat.

It is only loosely gregarious, males in particular tending to be territorial, but a group can be maintained provided sufficient cover and space is available.
