Best conditions for zoos

[mcfa2403]

I currently have a few zoo frags and they don't seem to open up that often, but some are multiplying already after a couple weeks. Currently I have green elephant ear paly, spider man paly, oarnge bam-bams, lunar eclipse, and one called poes red death. I really enjoy the way they look but feel as though they would look better if they actually opened up more often. I am not sure if they are wild caught or not but did order the two palys and the poes red death from reefhotspot.com. The poes seem to be the ones struggling most.

Current parameters:
Lighting 28g nano led (All but the lunar eclipse are currently on the sand bed)
Low-moderate flow (most likely on the low end where the zoos are placed)
Calcium 460
Nitrate 0
Nitrite 0
Phosphates 0
Alkalinity 11
ph 8.1

I know every coral will have slightly different preferences, but what would you reccomend for my zoos? Also, for future reference, what are some general preferences of zoos?

When mine do not open i tend to move them to a happier place. Some like more light and flow than others. I keep my temps at 78 degrees as well and they seem to fair well.

Different zoanthids like different conditions. I have some Japanese deepwaters that are 6 inches from the top of the tank, directly under my metal halide and I have bam bams that are on the sand bed, away from the light. Just experiment moving them around. Start by moving the ones that aren't doing well into more light and more flow.
