Freshwater Crabs

[edgun88]

Hey, I was wondering how you keep Freshwater crabs up. Iv'e seen them before at stores and I was wondering how they interact with other fish. Also do you have to add salt??

Funnily enough, i was just going to post something like this.
One thing i can help you with, is freshwater would mean no salt is required.
There are so crabs which are brackist which would require a small amount of salt, but seen as you're asking about freshwater crabs no point explaining it.

Hope you dont mind me asking questions too, i'd like to know a mimimum tank size. I know that they need a way to get to the surface, other wise they wont live as long.

ive had red claw crabs i was told they like a little salt but they weer ok in freashwater but they are good at escapingother than that use pellet to feed not that difficult to keep

We had a couple - more trouble than they were worth!

Escaping all the time - climbing up into the canopy and on to the light tubes, up the heater cable and out onto the living room floor. Only time we ever saw them was when we had to find them in the tank lid to put back into the tank.

I have a 55 gal freshwater tank... what can I do with it?

EDIT: Also if I wanted to add salt for brakish crabs, what kind of fish like brakish water?

post this in the brackish section and you should get a whole lot of info. also chck out the pinned topics in there as well. mudskippers make a nice "brackish" fish as they are amphibeous as well (need both water and dry land) but i don't know how them and the crabs would interact together.

ive heard that red clawed crabs need some land to be healthy

red clawed crabs do better in brackish water, they live longer, get bigger and are generally happier than in fresh, they do need land, they also really need a species only tank - though some people have them live happily with fish, most aren't that lucky, crabs are opportunists, they will take small fish when they can get them; large fish are a danger to the crabs (especially when they moult); I would seriously advise anyone against keeping crabs with fish. rainbow crabs are land crabs that you can buy in fish shops, they are often kept in water though they live most their lives on land, these crabs get large and are not particulaly suitable for keeping in captivity unless you have a large aquarium you don't mind keeping as a mainly terranium habitat.
