Help with zoas

[PokeFish]

Been noticing some polyps of my utter chaos dying. Started with one now its 2 … i wonder if something could be eating it? I do have cowfish… or maybe its being bothered by the pandora growing on it?

Check pests such as grey bugs, zoa spiders.
Assure moderate light and water flow
Also take a turkey baster and give it gentle blasts
May be mule which is a dust on it

Grey bugs look like little dots crawling around, and zoa spider are very tiny and live in the center of each zoa. Siders active at night mainly
Zoas must have iodide, not iodine in their water and under moderate light and water flow. They seem to do best in the lower half to third of the tank in an area of low-medium to medium-high flow. Too much flow may make it hard for the polyps to open. You will know your zoanthids are ‘happy’ if they open up and are fully extended without seeming to stretch so far upright.. The majority of zoanthids have symbiotic photosynthetic zooxanthellae (I dare you to try and say that three times quickly) and are therefore best kept with at least moderate aquarium lighting as mentioned for production of zooxanthele.
Zoanthids require the standard water parameters that are good for keeping just about any of your corals healthy. You’re aiming for water temperature about 78 F, salinity somewhere around 1.025 specific gravity) and normal hardness 8-11 dKH) and a pH around 8.1-8.3.
However, if your polyps were previously open and have recently closed up, this should be taken as a serious sign of a water parameters issue. The first things I would check are ph and salinity. In my experience, zoas will close up if there are swings in salinity.

I see thanks. I think i have found the issue as some parameters have been swinging lately

As previously mentioned- This alone will trigger the behavior you are seeing

Yeah just set up an ato… was kinda confised tho cuz all other corals seem fine… although now that i think about it the goni and frogspawn do seem a little annoyrd and so does the bubble
