My LFS has Blue Kerri emperor tetras and was wondering how well they would do with Angelfish. I’d get at least 6 and they seem more active than the black neon tetras that I already have. My two slightly larger than quarter sized juvenile angels do fine with the black neons and basically ignore each other. Would the blue Emperor Tetras be too active for the angels and even the black neons? Any risk of blue emperors nipping angels if kept in proper numbers? Or should I just stick with the black neons that I have six of and maybe get a couple more? Also what is the proper ratio of male to female blue Kerri emperors if there is one?
