I bought two Fiddler Crabs today which are currently in a temporary tank while I set-up their permanent home. I was curious to know if anyone else keeps these, and if so, how their tanks were set-up? I wasn't particularly fond of how their tank was set-up at the store, it was mostly water with only driftwood branches sticking out here and there for the crabs to get out of the water on. I haven't come across specific land:water ratios, but I was hoping I could have more of a land area for my crabs than that. If not, it's no big deal... I mean, they seemed just fine as they were in that tank, it's just not my favorite idea of something to replicate in terms of decoration.
