need help with zoas

[SSLEWTER]

I have had some bright pink zoas for about 6 months now and little by little they die off. they are in the middle of my 20 gallon long tank which has a 175 watt MH about 5-6 inches off the surface. I feed my corals kent micro vert and kent phytoplex. My levels are pretty good. I do have a nice (not) population of glass anemonies. What can I do to help my zoas they have an awesome color that I want to keep in my tank.thanks

Have you tried moving them down? Zoanthids usually proliferate like bunnies!!!!

What fish do you have? I had a blue damsel and a green clown goby (my two favorites) go after my golden polyps.
