That’s a flowerhorn for you. Although I think they get their crazy aggression and pure nastiness from the amps. Red devil/midas. My red devil was 6 inches before I had to get rid of him and in one night he ate 6x 2-3 inch Buenos Aires tetras I was trying to use as dithers and absolutely shredded up my 7 inch Jack dempsey. I find my flowerhorn to be much more tame but still actually show their aggression while amps are like the psychopaths of cichlids. My red devil would the calmest fish in the world but when it felt like it would go ballistic and purge on all the other fish. I definitely want to try keeping another one in the future possibly a midas but definitely solitary next time.
