When I first found these animals, I took them out and placed them in a smaller watch glass to examine them under a dissecting microscope. They proceeded to copulate fervently! Upon finding the larger and greener animal, I again removed the two color forms and placed them in a watch glass to facilitate photographing them. Once again they immediately starting copulating. I had hoped to get a photo of this steamy action, but couldn't get them in focus. I haven't noticed any egg masses, though, so Kathe's point regarding viability and fertility of offspring is still unanswered. I'll keep looking though. Bill, I have moved them all into the aerated tank, but haven't had a chance to look for the browner morphs. Your point is well taken and I would hesitate to call these separate species.

Isn't great studying live animals? I look forward to progress reports
