Hi everyone, I have 4 zoa frags in my tank. three of the look normal ish however one of them has been slowly shrinking in terms of polyp size of the zoas for a couple months.
I am including pictures below. My rainbow incinerators always had small polyps but isnt growing much. I have CB rainbow infusions which are on a different ledge and are fineMy utter chaos wont stop growing and is doing well with large polyps, and my rastas are the ones struggling.
I was having a cyano issue which actually went away once I started feeding MORE, possibly due to a nitrate phosphate imbalance. I think my chaeto has picked up since then as well, so now im trying to home in on whats causing issues with these zoas.
The tank also has a few pieces of SPS which are thriving and growing like crazy.
Does anyone know what polyp size like this could be indicative of? low light? high light? low nutrients?
