Ok so I have a 90 gallon reef set up and want to start buying some softies for the tank. However I have a pesky Blue Damsel in there from the days of the tank being a predator tank. He is attacking my strawberry dottyback and I want the damsel out. Anyone have a clue on home to catch a Blue Damsel n a 90 gallon tank with 100lbs of rock work? Haha, thanks if you ahve any cool ideas.
