Can't figure out what is wrong with my Utter Chaos

[Mightyfish]

I wonder whether anyone has experienced these with their utter chaos. I bought 2 frags 4 to 5 months ago. One frag has only 1 polyps but shortly it shot out two more polyps. Eversince when one becomes three all polyps size are tiny they are like micro zoa and the two new polys are the size of a dot. Polys are opened everyday but never fully open i dont see their frills. Been like this for a few months now.

Second frag has 2 polyps and they are more normal size. Not sure whether it was because i placed them higher (about 18 inches from Radion light), they have lost their black colour. Now they dont even look like Utter Chaos just a bright red zoa.

Any thoughts on the above would be great.

Do you keep other zoas as well? How are they doing? I have had a few different zoas shrink real small due to some sort of stress I never figured out but came back. Might be a lighting or flow issue.
