 How do I catch my fish
I have this Christmas Wrasse that folks have said is bad, and I think perhaps he's taken out my peppermint shrimp, and maybe even hurt my clown, so I want to take the guy back to the store (yes, I've already been scolded for the purchase without the prior planning and research). However, I tried catching him tonight with no success - tried luring out with food, "herding" into a net and had no success. He eventually buried himself under the live rock. Was wondering, with the live rock, does anyone have any good suggestions on getting him caught and out without having to dismantle the tank and without stressing the other guys too bad? I've had using a red container somehow in the tank as I guess fish can't see red and I've had putting in a bottle with food and hoping he swims in then yank it up. Any other thoughts?
