So I got an emerald crab 3 days ago. I have seen him once since I have put him in. What I have seen is the remains of 2 hermits that he has killed (haven't seen him kill, but has to be him).
Does anyone have and emerald?
I know they are nocturnal, but do you ever see them during the day?
Do they kill everything they can get there pinchers on?
Do they ever eat algea? I got him to help keep things clean, but haven't seen him clean anything.
I guess my main question is why have one if you never see him and he kills other crabs and snails at night? Is there anything good that they do that outweighs the bad. If not he is going back to lfs
