My Goby is screwy

[OCDP]

Maybe he just adapted to the QT tank conditions, and now that he's in your display he needs to re-adjust. I still think some sand would do him some good. After a bit of research and what not, I decided when I upgrade , if I go BB I have to get rid of him so he can live happily in the proper environment. But, if I choose to keep him, then I'll need to put some sand in my new tank. They love sifting through the sand with their mouth (at least mine does) Really cool fish... and they're super tough.
