Hello all I just recently purchased a kk that has alot of red devil in him. My wife and I have given him the name Ares. I had him in with a 8 inch male jd and a nale 6 inch salvini had to rehome both over to my 75 due to the serious attitude of the new kk. What are suitable tank mates, also how can you tell the sex of a kk? Was also thinking of finding him or her a bf or gf was wondering what would be a good choice.
