Rainbow Acan Stopped Opening

For about the past week my rainbow acan has stopped opening its tenticles and eating. Last night a few of the heads were opened a little larger with a few tenticles out, but that's about it. My water params are all in check and I've been on a regular feeding schedule of every other day. Any thoughts, ideas, suggestions?

did u have a temp swing

No temp swing. I run 2 heaters just in case 1 shuts down. Temp is constantly at 78*

is it near any other corals that might sting it? and could a fish or invert be picking at it?

Not within reach of any stinging corals. The only time my inverts will pick at it is during feeding....thieves! My fish don't pay any attention to it. My scooter blenny will glide along it as it cruises the sand, but that's about it.

how long have uhad it

about 2 months

were is it sitting in the tank. and how muck flow does it have on it. they like lower flow and a moderate light

Also, it's possible to OVERfeed. It may still be processing the amount of food it's already been fed. You need to allow the acan to expand or the heads will collapse. Good luck!

I have it on the sandbed so the light can't really get any more moderate unless I put it under a rock ledge. The flow is the same as its been since I put in the tank. The flow it gets is deflected from the front glass. The flow was hitting it too hard and moved its angle, but that was on day 1. I actually haven't moved the acan at all since I first put it on the sandbed. I've been feeding it every other day since then as well and it's been having polyp extension just fine up until last weekend. Maybe its just acting a bit finicky and will get back to normal.
