I'm thinking about setting up a 5 gallon fiddler tank.
My first question is, what's the best way to set up a fiddler crab tank?
Also, Are they loners or do they like having another crab?
If I get two crabs would it be overstocked??
They don't really move around much.. I don't see a 5 gallon - 10 gallon tanks being a problem. Just make sure the top is closed off -- Mine tends to crawl out if I don't tape up the back.
And don't put them with Puffers. My Figure Eight bit off 3 of my crab's right legs, forcing me to setup a 2 gallon.
