Crab Community Tank

[Aquaman187]

I seen some really cool crab at my lfs and I was curious as if they could live with any other fish.

What crabs were they?

To be honest most of the crabs I know of aren't suitable with fish.

pretty much anything with pincers is a no-no in a community tank.

also, almost all of the crabs offered in the trade require brackish (slightly salty) water and access to land - as they are predominantly land based creatures.

had a pair years ago. they would sometimes grab onto the fishes tails as they swam by and hold on for dear life. they are escape artists too, i came down one morning to find one had made its way through the living room and into the kitchen.they got out a few times and i wouldn't have them again

i used to have two Red claw crabs, a male and female, even with the area requirements per crab they fought a lot, but it was probably due to their species temperament and the only way to surface was on the same log.
anyways MOST (99%) of crabs sold in a lfs are brackish crabs,(petco just recently switched their redclaw and fiddler tanks to brackish thank god. freshwater crabs don't reproduce like sea crabs and ergo there are fewer of them with less diversity due to non connected lakes, in fact most are endangered.

fish compatible with crabs are those with short fins, less likely to get nipped at. and fish that arent bottom feeders or rest on the bottom often. But the larger your tank they more compatible fish and crabs become. I would personally go towards a crustacean that doesnt need to surface, such as a shrimp or if your tank is huge then a crayfish, that is because since they dont surface, they will have less area they can move to get a fish. But id avoid Red claws all together. they are boring, fight, and hide, hence the boring.

alot of lfs carry red claws so if you do get one i suggest two females with 1 sqrft of space each or one male with the same area. also my reddies looooved sliced carrots


P.S. just found this video, as you can see a redclaw has no problem killing.. found a fishy, ate the fishy.

Hi, I have a question you may be able to help with: I just posted my questions, but to make a long story short, I just bought a mini fiddler-type crab from the pet store, 1 3/4" wide, has two identical sized main pinchers, turns from brown to cherry red normally, don't think its a true fiddler crab, but I just found out that crabs need salt in their water, do you know if this is true? The store claims this crab does not need salt. I happen to have natural sea salt without iodine and do not know if my tank with fish and crab need salt or not? Can you advise with any suggestions? Thanks very much.
