Hey guys, im thinkin of keeping "the devil" or red devils. I know they are extreemly aggressive but is there anything I can add with them? I was thinking maybe large tetras. something fast. The tank is 75 gallons is this enough room for atleast one Devil to live conftorably? also are Red devil's primarily carnivores so can I feed them both frozen and live food (feeders fish, shrimp, etc)
