Here is my problem. I have in my tank now a Percula Clown, Dwarf Coral Beauty Angel, 20 dwarf hermits, 20 snails, 2 emeral crabs, and 3 pepermint shrimp. What I need to do is remove the Blue Damsel. I want to get him out because he harasses my clown constantly, and he was just a test fish to start anyway. I was wondering if anyone has any suggestion on how to catch him. My tank is full of live rock, as you can see in the pic, and I don't wanna have to move or take anything out. And since he isn't gonna just swim in the net, I was wondering if someone had a good way to catch him. Thanks!!
