ive got a 33 long reef tank with a variety of corals but for some reason my zoas just keep disappearing...one day theyll look good and then the next i notice they are closed up and looks like there arent as many on the rock.all my zoas are doing this.my parameters are in good standing.i dose phyto feast and one other liquid food,and then the normal foods.is there any kind of bugs that i could not see that could be eating them.ive only got a purple tang,2 clowns,diamond goby and a purple lobster in this tank as far as fish.ive never had a problem keeping zoas so this has really got me bugged.what can i look for or treat the tank with to get them back to being happy.thanks
