I never said that zoanthids didn't like high light.
My zoanthid tank is only 18" deep and I use a 250 watt PFO HQI ballast with a se 14k bulb.
My zoanthid tank has been doing very well with that light.
My tank has over 2 dozen different zoanthids, palythoas and protopalythoas color morfs.
I did say many blue zoanthids don't like direct mh light.
I've had several blue colonies that just turned grey. Many people I know around the country have reported the same thing on several other forums. When blue zoanthids started showing up 7-8 years ago, many of us displayed them up high, where they were very visable. Some left them in shaded areas. Everybody I know or read about complained about the same thing. They faded.
I recently bought a frag from a LFS of blue paly's. I left them out in the open. They faded.
The colony at the LFS is under a overhang and still blue.
One of the exceptions are the Tubs Blues
As far as food capture, when I feed my tank, only the protopalythoas, palythoas, and some of the pe types show a feeding response. The rest do not capture food. Some will close up as a defense response when the food hits them, but they open up almost immediately.
It maybe that zoanthids get nutrition from the water as the food we add for fish becomes a slurry and absorb it somehow that way.
I add Sea Chem Reef Plus, which is a vitamin and amino acid supplement
But I still say most zoanthids don't capture food.
This is what I've learned in 18 years of keeping different types of zoanthids, and palythoas.
