Thanks guys, a little bit more knowledge in the brain cells. Looked up both on Google and would have to go with gracilenta. What I did learn was to look for specific markings and detail before i put them back. These litttle fellas should have a blue marking on the inside of their rear legs, which i didn't even notice. They tuck up pretty cute tho' don't they. look as solid as tanks. They aren't that common so I'll try and make them a more secure habitat and get rid of the goldfish. Goldfish swallow little taddies like sweets.

thanks again
