Yeah, so the update is this. It was a Black not an aimara and eventually, probably after being provoked by an over zealous Azul, he grabbed the Azul by the Pec. the Azul was 13 inches. I choose to remove the black wolf which really sucks but I got tired of worrying about it. Rays and Bass, works for me. The black is now about 16" and is in great form in his own tank. My aimara will never be given the chance to hang in the 600 he is way too aggressive. If I get my 2500 I might try it again.
