Heat-shocked zoas, will they recover? (pics)

[zachfishman]

Last week my tank temp got a little high (forgot I left the cooling fan off after a water change; tank got to mid 80's when it usually is ~80). My green zoas which had been doing great (pics below) were closed up and have been ever since. No other corals, including my other zoas, were affected. Anybody have zoas stay closed for a very long time and then come back ok?

they look fine. give em a little more time

I had an accident a few years ago....tank hit 94 and while most of the tank was toast, most polyps survived, and many of them didnt look that good in the days to follow

plus 1 give them some time

Good to hear, thanks.

How much time do they need? It's been another three weeks now, and they look exactly the same. Good that they haven't shrunken more or melted/deteriorated any, but still I'm curious as to whether things will turn around.

One possible irritant is my peppermint shrimp. This morning I discovered that it was the reason my ric was dieing - it was picking at it. Maybe it's picking at these zoas too, but it would be odd that it would target these and leave my other zoas alone...

Before I gained more knowledge on aquariums a few years ago my water would always hover around 86-87 and never lost a polyp.

I had some zoas closed up for more than a month and they opened again; minus a lot of color, but the color is recovering.

Sure it's not the goby perching on them? Is that a new habit?

There are quite a number of things in the hobby that can take higher temperatures if adapted properly and sustain that level. However, drastic swings in any direction (hot or cold) can be a bit more stressful.

Sorry it took me a while to respond. It's definitely not the goby, as it has not perched on them since I got my trumpet (where it now perches), it also never bothered the zoas even when it did perch.

To update, the zoas have slowly begun to come around. The peppermint has been gone for a week now - they began opening the day following shrimp removal.
