Is it possible to house 2 bimacs in 1 tank? The tank is a 150 gallon. I have heard conflicting info on this 1 LFS told me yes it is possible and I have done so before, another said absolutly not 2 will fight to the death. Another question is it possible to house a lion fish or a sting ray in the tank with a bimac? Once again I have heard conflicting info and the same results from the 2 LFS's.
