What is the best way to catch a fish in a reef tank. I bought an Eibli Angel from my local fish store which they said would be reef safe but it isn't. The darn thing is nipping at my green brain coral. I need to get it out ASAP. I've tried the nets but ther isn't much room. If I moved as many of my corals off the rocks and took them out of the tank for a few minutes would this screw up my tank. Please help!
