Wow, really? I did'nt know that. I really could'nt see him too well. He's smaller than a dime and I only really got to see him sticking his claw out to get some algae to eat. He's REALLY tiny with white tips to his claws. That's about the most info I can provide so far. I'll keep an eye out for him. This is my first tank ever and it's only a month and a half old so I'm learing a lot every day. Thanks for the heads up.
