Mini hermit crab tank
Hi, I really like little tiny hermit crabs like blue legs, red legs, and zebras, and I kinda want to start up a little tank just with hermit crabs. I don't know where to start though.
What size tank would I need? I would only want maybe 3 or 4 crabs.
Would I need a lot of live rock? I'm fine with getting a little bit, but I wouldn't want to get a ton.
Would I need a powerhead, sump or anything like that?
Anything else I'm forgetting? I know I would need a heater, filter, refractometer, and things like that.
