Zoas not opening

[Millsaps2378]

So for the past 3 weeks or so my bob marley zoas have not opened up. When I put them in the tank I put them in a med flow and med light spot and they all fully opened for about 3 weeks then for some reason now only 2 or 3 heads will open up. I have multiple zoas around them and other corals in the tank that are doing great but it's just those that won't open. Water temps and params have all been normal and I havent moved or touched them hoping they may have just gotten upset from something but it's been 3 weeks now. I feed oyster feast once or twice a week so they've been getting food and they are not touching any other corals. All the heads look to be in good shape, still normal color and I can't can't see any kind of pests or detritus on them. Wasn't sure if I should just let them do their thing or if there was something I could try. Thanks for any advice in advance!

Some zoas are low light and flow. Some moderate and some actually like higher light and flow. Perhaps yours need to be moved.

Might have a fish that is picking at them. Or you might have a bacteria or other pest. Might be good to try a dip and look for suspected fish.
