I have 6 small (1.5-2") green terrors in a 35 (temporary while I wait for my 75 to cycle.) I have a friend that wants to get rid of his green terror because it keeps picking on his convicts. His is probably 2.5-3" but much thicker in the body than mine. Probably double their overall size. Would I be ok to add him or should I let him find a different home?
