I just got 3 of these guys. I need help with setting a tank up for them. How many should be kept together in a 10 gallon. I need a How To for making my 10 gallon brackish. What substrate will I need, since they will live in shells sand would be best, but can it be gravel? How do I set up the tank, should it be bare or do they need plants?

a few plants wouldnt help but sand is a good idea because they will lay and burry in it sometimes. also large smooth pebble type rocks will be happily perched upon.
