Also I have a bichir (senegal I think) sitting in my cichlid tank, thought it would be okay to add him to the stingray tank, hes about 6-7 inches right now and the ray is about 5
I wouldnt add the senegal, my buddy had his 3 year old retic ray get both his eyes plucked out and he had to put it down :-( Dont trust bichirs!
