does anyone have red devil(s) that just hide all the time under rocks, sometimes even on its side?? my red devil is vicious, but all he does is hide and never comes out. does anyone have any clue about this behavior?? i had to separate him from the other fish due to aggressive behavior, however, he backs down to my red jewel. are red jewels aggressive cichlids?? the red devil killed my jag yesterday, just a little smaller than him.
