Im sure this has been asked before so my apologies. I've had two occelaris clowns (one black, one orange)in my tank for the past year and decided they need a home. Just purchased a nice healthy RBTA that is doing great in my tank. Questions is, how long does it usually tank the clowns to host it? I've heard anywhere from weeks to 1 year. Also read about people taping a picture of a clownfish/nem to the side of the tank to help?
