Some of you may remember my previous thread about saving this guy and now I have. He is about 10.5 inches and has serious HLLE. He hasn't eaten any pellets or even the crickets or worms I tried to give him. I threw in four tetras and three have disappeared. My question now is what should I do to help him recover? And as the title says he is changing color. Not gradually but like flashing different colors. He is normally black with red on his sides but occasionally he will turn almost green, then after a few minutes he will flash back to black almost instantly. Its amazing to see and I'm curious why he is doing this.
