i currently have a 55g because my 125g exploded.
in the 55 gal i have a red devil, v fenestratus, texas and a green terror. with 2 cons and 2 giant danios as dithers. they are still relatively small and have been doing fine for a few months now. red devil and fenestratus are deff the bosses of the tank.
i know the answers are going to vary but in your opinions with good filtration and hiding places could this work in a 125 for life? i also accept the fact that some devils are just vicious killers and am willing to part with mine if that is the case. aside from that i think it will work, but i would like some other opinions. thank you.
