You have no idea how happy this post made me - the fact that you can keep a single ram is amazing! I always flock to them whenever I go to the fish store and really wanted one but wasn't sure if they could be in a community tank, let alone a sorority. Might have to get one now...they are so cool.
Oh I didn't know keeping a single ram was a problem actually
I do plan on getting a male but at the time I didn't know how to differentiate them and then we had the ick situation. She's really funny to watch though, she makes little concaved areas on the sand and chases off anyone who comes near her spot. I hear that they aren't too difficult to get to breed in tanks, I guess the biggest issue is other tankmates eating the eggs.
