Green Button Polyps

[PsuedoHippy]

This one should be pretty easy for most of you. I got a colony of green button polyps about three weeks ago and cant seem to figure out what part of the tank they like most. I have a 54 gal. corner tank with a coralife dual 65w bulb with one being a 50/50 and the other all atinic. In the rear corner I have a pendant syle coralife 175 MH with 10,000 k bulb. Problem is when I have something near the front of the tank it mostly enjoys to compact fl. bulbs. If I put something up higher near the rear it get a good blast of metal Halide. My button polys originally were more toward the front. They seem to open themselves up too much. They really spread out and no longer have any cup shape and all, in fact they seem to open backward a little. I figured maybe they needed more light so I moved them into a prime spot closer the the halide. They still are the same way. Does anyone know why this is? They have what I would call medium to strong water movement. Maybe more toward medium I suppose.

my green button poylops when at the top of the tank 6" from 4 96watt compact flor. stay very short and open well. A piece I cut off and put in the shadow in middle of tank brace stretch out 3/4" and open well. I have had button poylops (brown) in a customers tank for a long time. They are like weeds in bright light, dim areas, low flow, high flow. they dont seem to care. Could you be giving them to much light?

I'm trying to get a visual of what you mean. This is a horrible picture I have, but this is what I am picturing about your green button polyps?

Thats It

My button polyps are definately cooler looking then that but ya the polyp part is bent back like that. So are not quite so far back but close.

Isn't that why they are called "button polyps"? (the shape)They will be happy if you feed them small meaty morsals pretty much wherever you put them.
