So I have a question on emerald crabs... I got two so they would take out some bubble algae and be a productive member of the tank. But instead I come home to the two of them tearing up my birds nest. Needless to say since they were embedded in the nest it made them easy to remove. Now comes by question, What do I do with them? I currently have a fairly large rock crab in my sump and don't know if they would all fight? So I ended up putting them in the over flow box for now. I hope they don't make their way out for the time being. Ideas? Anyone want coral eating crabs? Just Kidding...
