freshwater crabs?

[Knereim]

Do I need a dry dock in my tank in order to have them or is in not possible with my tank (getting really modeled tomorrow) would like to add them with remodel

There are tai micro crabs, they complete their whole life cycle underwater. However they're pretty small. I believe for other crabs your need a piece of land above the water level. But Beware, some crabs require brackish water, I believe one is a fiddler crab. I could be wrong on that though. Hopefuuly somwome else will chime in

Yes, fiddler crabs are brackish, and yes, most "freshwater" crabs will require a land area of some sort, and seeing as they can't swim, you'd need to make the dock reach all the way to the bottom

Will fiddlers die in my 65 if there's no dry land?

 

[Freakgecko91]

Fiddlers are brackish, meaning semi salt water, so I'd say it's highly likely that yes, they will die dry land or not

I also have marble Molly's Rosie barbs and a rainbow shark I was told they were brackish

 

[Freakgecko91]

Mollies, yes, barbs and a rainbow shark, no. Not to mention are you really willing to spend a significant amount of money on salt (not aquarium salt, marine mix) just to keep a crab in your tank? Not to mention major remodeling of your tank?

No no was just wondering and trying to raise my knowledge on my tank
