Thanks Nick! Yeah sometimes I don't do too good of a job handling it myself I'm glad they're high grade! I went back to the same LFS and got more, and I *think* I got all males but at least 1 of 3 I think must be males. after acclimating them I put one in the 2.5 gallon with my brand new resident, 2 female RCS. They all seem to be acclimating well to the different tank. I put the other 2 potential males in with everyone else in the one gallon, so we'll see what happens.
