That I'm not sure of. I guess it would depend of the fish and what you keep with it.
Due to cycling issues when I first got my green terror I had to put it in a 10gl with 3 glofish tetras. She was only 1 1/2in at the time but killed one of the tetras.
Got her put back in the 75 fast forward to her being 5 1/5-6in now and a jack that is about 4in. I'm thinking the jack may have to go. The terror keeps the jack in a stump and only lets the jack out to eat. Then chases her back into the stump. The terror is also aggressive towards my pelcos.
I lost all my guppies to either the terror or the jack. Since the guppies slept up at the surface it made the easy targets.
That has been my experience so far.
