this is a serious post and am not looking for attention. it is a question that i need answered. these fish have become extremely agressive to my dismay, especially the damsels. i have tried to catch them to take them either back to a pet store, or to put them back in the ocean, but this has been a tremendous task in which we have not had results. my tank is extremely large and my fiji rock are glued together. dismanteling it to take out these fish is not an option. in fact, this may be an impossible task, for the rocks no longer fit through the upper hatch. i guess it was poor planning on my part and i should have researhed these fish more thoroughly, but these fish are taking away from us enjoying our tank. any suggestions?
