Is it possible to have to paradise fish in one 55gallon tank....even if they are both males, I ask this because i ended up buying two paradise fish from my LFS and there was no way to tell if thew were male or female and it looks like the one has become the dominant fish and the other one iw a little torn up i am not sure what to do i dont have anywhere else to put the paradise fish and the store won't take it back.....what should i do??
