That is cool. I have one in my sump. I have had him for 4 years now I guess. Do your eat fish? I am afraid to move him to my display because I fear he will. I can't believe they all live together. For sure moray food in the wild.
He is mean also. He has gotten my fingers a couple of times. Once I yanked my hand out and he flew across the room. Leaving his claw on my poor bleeding finger.
I don't think lobsters go through a planktonic stage. So those could very well be babies. They grow fast so you won't have to wait long to see. Keep this thread going and let us know.
