Ppl need to start providing a lot more cover for the fish who have to deal with a MIDI/Devil especially one like mine..if fish cannot hide ior get away they will kill them point black period I don’t care if it’s a piranha which I’ve owned..ppl need to know male devil is like a water dog he can be ur best friend but he can bite you,can and will exterminate any tank mates as you saw I avoid by a 125 with tons of cover...you will come to love them my whole fam loves him now but they can be pissy,mean,destructive and without cover The other fish stand no chance
