The time has come.

I guess the time has come for me to break down the tank to pull every single Damsel fish out of my tank. I bought a Kole Tang last night and one of my Damsels has claimed on side of tank and i'm afraid he is going to stress the Tang to death chasing it around the tank. Noob mistake on my part... Never again.

If your damsel are not big, you can make a trap with a coke or a Gateraid bottle and bait it with their favorite food.
You may be able to go fishing with a tiny barbless hook like H@rry does and catch them.
Pulling rocks out is a viable option if your tank is not too big and you don't have many corals.
Of course I'm the one who took down an entire 180 to catch two 1-inch fish... but I tried other methods, too. I caught most other fish but these two little guys.

Thanks for the tips. I ended up just pull all the rock out since I only had three frags in the tank. I was at the point where I was worried the tang would go bottoms up if it continued.
