fiddler crabs escaping

[glommes]

I noticed that a lot of people who have fiddler crabs have mentioned that they are escape artists. I can't help but wonder how they get out. Surely they don't climb up the side of the glass. Do they climb up the filter or the heater?

yes

they need a species only tank, brackish too. They won't like the FW which is one of the reason they'll keep trying to escape, they need the calcium in the marine salt. They also need a really tight cover.

What if your water has a good rate of calcium out of the tap? Will they do good if they have some land? Or is there something else they need from the water?

My experience is that these guys will not last long in Freshwater...maybe a few months.

Although I've never actually kept fiddler crabs I was once considering it and I did a lot of reading about them. First of all I gathered that they're brackish water crabs and do best in brackish water. Second they do need access to land. For this what I was going to do was buy one of those things made of plastic that floats on top of the water and then i was going to use fake vines to anchor it and give the crabs something to climb up. Or I was going to make a very large pile of rocks that went above the surface. Also I read that they sure will climb up filters and anything else they have access too. Make sure everything's covered. Hope this helped. :)

In my reading I have seen that they are breeding freshwater Fiddler crabs. If this is true how do you tell the freshwater ones from the brackish?
