I've decided to call them Dr. Jekyll and Mr. Hyde. I can already tell them apart, Hyde has a circlish marking near his tail. I'm calling him Hyde because he jumped out of the cool whip tub twice while I was getting their tank ready. I even had a lid on it, there was only a half inch square opening at the top. After he jumped the first time I put a sponge over the opeinging and Hyde got out yet agian, the litter bugger.
Anyway, my new little loaches are doing great, they've made themselves at home.
