Patriot Crab (Cardisoma armatum) Info

  • We are currently upgrading MFK. thanks! -neo
Are these crabs aggressive towards other creatures at all? I was thinking about buying one to put into a 125 gallon tank when by snapping turtle got to about 4", along with a few mini crabs and smaller fish.
 
Vinny looks like a female maybe? Any way they love to burrow, and one half of the tank should be entirely dry. You can feed a mix of things like fruits, veggies and other things. I wold avoid feeders bought from stores as they may carry decease. Also when they molt they may often look like they are dying while upside down, do not attempt to help, they will get through it. They can be aggressive but some can be friendly of sorts. Now when you buy these they may say they are from Africa but many come from Florida nd some Caribbean islands, and called Patriot crabs. Reason being is that many of the giant blue land species as young crabs have that purple/blue head and orange legs and claws. The water should be in a bowl recessed in the gravel/mulch material, this is beast for easier and more frequent water changes. Also if you handle them a whole lot they for some reason tend to become lame and die, so limit the handling but offering food is okay.
 
these crabs u saw them over at my LFS are around the size of my palm and man anyone tried breeding them ?
 
Hello! My wife has been taking care of Patriot crabs for about half a year now, she has 2 of them. We've seen the male molt twice now and it happens over night while we are sleeping. Yesterday i got up and saw the female sitting in the sand with her claw in the sand, figured ok she's just chillin. Get home from work, in the exact same spot... same position as the morning. Today she hasn't moved still. We don't wanna touch it until we know for sure if its dead or not. Its been fine and digging and going in the water and everything just normal. Then all of a sudden it doesn't move for 2 days. Is it in the molting process? or is it dead?? Thanks.
