Fiddler crabs

[Torrey45]

So I was thinking about getting some fiddler crabs for my ten gallon tank and I was just wondering if anyone could give me some info. I already know that they need brackish water and a beach or something. I would like to know more, like how many can i have. I've also seen different species and would like to know which would be best. Thanks

I have red claw crabs in a planted community 90G if you get a male and a couple females they wont fight and also they need air and will climb to get it UNLESS you look into one of these which I have and seems to work well www.crabhomes.com fresh air and dry land at the bottom of the full tank!
