info please on this button polyp

[apexi]

I didn't realize we had a Zoa specific section so I'm posting this again here:

I have had this button polyp in my 180g for a couple weeks. It has been doing great until just a day ago, when I noticed that the top section of the colony isn't opening up fully. As you can see in the picture that I quickly snapped with my camera phone, it's not fully closed but not fully open & extended either. Any idea what may be happening here?

Water parameters seem to be good with Amn 0, Nrite 0, Ntrate 5ppm, Phosphates 0.1ppm, calcium 450ppm, 7dKH, ph 8.07, salinity 1.025, temp 79-80F, RO/DI. Plenty of waterflow and MH lighting. All the other corals are bursting with life (xenia, kenya tree, bubble, open brain, frogspawn). The button polyp is spaced far apart from the other corals. Does anybody know what specific species this is as well??

I also noticed that there are tiny "stubs" that seem to be protruding from the center of some of the polyps, as highlighted in the photo below. I don't know if this is related to some sort of reproduction, or something else attributing to the semi-closure of this area of the colony?

It kind of appears like it is the start of zoa pox. Can you get a closer picture?

I don't have any closer pics at the moment. However, it doesn't appear to be zoa pox, since I don't see any white spots on the sides of the polyps. The tiny knob like protrusion in the center seems to be coming out of the polyp itself.

Here is a closeup of the polyps that aren't opening fully. You can see some kind of stub like extension protruding from the center. Anybody know what this is?? The rest of the polyps are closed tight, however even with the lights off and even if I touch these polyps with my gloves, they don't close up. Are they dead??

i would reduce light some, to help the zoa readjust. dip with Lugol's Solution to help kill off any other adult nudi if there are any still there. Examine all the polyps for egg’s which you can scrape off. monitor the zoa later at night after a couple hours after the light go out. turn on your actinics then you can use a turkey blaster to sux up any as well. Wresse might help keep them in check.

This has always worked for me in the past. The key to eradication is persistance. Even after you think you are nudi free, you can still have them. Hang tough my friend.
