coolest, most unique idea ever. The thing is that you cant put crabs in the tank. Crabs are best left by themselves, because they will find almost every moving fish a food. If you have a crab only tank, then you must make it escape-proof. The crabs need a place of land to rest on, and they are great escape artists.

Also, how tall is the tank?
