How often do Fidler Crabs molt?

Question

I just bought two crabs; one male, one female. I am diligently researching what I need to do to keep them happy. I have 3 aquariums of fish, but these are my first Fiddlers which are in their own 10 gallon tank. I've read they molt, but not how often. Also, has anyone ever been able to breed these crabs successfully? Thanks in advance for any advice!

Answer 1

Fiddler crabs molt every 2 months.  As for breeding, it is almost impossible in captivity since the babies float in the ocean for a couple weeks feeding off plankton.
