Sun Polyps won't open

[ScubaDiver93]

No matter what I spray on them I can't get them open. I have tried phyto and mysis and they still wont open. Not even at night.

Is there something bothering them?

I usually spray some cyclopeeze to get them to open up before feeding them frozen food.

its important to ge them eating. Take them out of the tank and put the coral in a bowl with tank water and a lot of food. Put an airstone in the bowl and leave them in there for 30 minutes

Try dimming the lights down to just actinics or lights off. Feed some zoo or phyto plankton, cyclops or just some juice from some mysis. Wait for upto an hour for them to open. Sometimes cutting the flow will encourage them to open. They can be finicky buggers. I've got one colony that sometimes doesn't open for two or three days. Don't panic,
they are fairly hardy. I had a bit of a tank crash and mine didn't open for about 7 days. They all survived.

keep the lights off for a full day and see what happens

when mine didnt open i placed formula pellets on each mouth, took a while but it started to eat.

i had to put a flat rock over them so they are in an overhang, then i target feed them with the filter and flow off for 30 minutes
