Re: emerald crabs

Yes crabs do molt.
Your sacrifice may have just been a molt.

Re: emerald crabs

most inverts molt lobsters, crabs, shrimp, etc. thats what you saw i have never had crabs reproduce, and you should not see two live emerald's right by each other because they fight

i have a sure way of checking to see if a dead looking shrinp or crab is really a dead crab or just a shell take it out of the tank and smell it you will know right away if it is a dead animal

All Crustaceans will replace lost limbs by their next molt or two, but not at the same size as the lost limb.

Re: emerald crabs

Yes, it will eventually over the course of a couple molts get back to normal.
