They are nice! I have got 4 recently (friday), and I saw them for the first time since putting them in the tank, today. They were inside the cracks in the bottom of driftwood, I noticed them when I was cleaning the sand underneath!!#
Mine are tiny though!! Very thin, I hope they will get big and fat! They also came out of their own accord a couple of times. They swim very funnily!! Not unlike my weather loach, just smaller and less destructive! I guess they'd be happy in my tank. Sand, plants, wood mmmmmmmm.
