"Freshwater" Crabs

[mellowvision]

they do, and they will spend a LOT of time out of the water. mine spends more than 50% of his time on land. they are a lot of fun... and in my experience are too slow to catch most fish. mine gave up trying after about a half hour.

also, they should really have about a square foot of floor per crab... you don't want to pack them in the way they do at the stores, this will only lead to lost limbs and eyes.

I found out after a longer search and a site with accurate photos, that I have Fiddler crabs. They need an area where they can get up out of the water, be it land or just a pile of rocks and shells.

I am not sure about red claws, but it can't hurt to have a spot for them to get out if they want to. I think it all has to do with the natural behavior of the crabs. Are they tidal feeders that run across land at low tide and look for food? Or are they deeper water and never come out of the water for any reason.
