I've had a coral banded shrimp in my tank for about a month now. About a week ago I saw what appeared to be a molt in the tank. His skin was on one side of the tank and I saw the shrimp hanging out over on the other side of the tank. Everything seemed fine over the next few days. The shrimp was eating and looked to be doing OK. Then, today, I noticed that he no longer has either of his claws. Both arms are gone. He still has all of his smaller pinchers and is moving around and eating fine, just without his large claws. Anyone know if this is normal, and if so, will he grow them back?
