Polyp Extension at Night

Well i cant get good pics because my camera wont pick up anything worth seeing, butt I woke up Friday night (well night for my tank about 8:00am) to check and it turns out I have a ton of bristle worms haha! more than i imagined! About 6 of them were out, im sure there is more lurking. As far as I can tell I have zero pests, bristle worms don't mess with the acros it seems, they never have any marks or anything on them. My parameters are within perfect range and holding stable. I check them every week on Tuesday. Salinity stays constant, check that every day. ONLY thing about pests I could think of is since my one emerald crab (smaller one) died my bigger one (I only had two) seems out and about A LOT. He might be scurrying along the base of the acros looking for food, or possibly nipping for polyps because hes hungry. This has happened to me before but it was VERY noticeable, the thing sniped a tip right off, leaving a white spot! So I don't believe this is the case here but im not ruling anything out. I haven't seen any tissue damage or irritation other than what I cause with my clumsy hands when rearranging things.


Anyways when I looked at night it seemed that one of my acros that don't extend much during the day, my lokani, showed a small amount of better extension at night. However what baffles me is that my mille's have almost zero polyp extension at night and are fully extended during the day. Could it be that I feed when the lights are on and at their peak once a day everyday? No need for polyps at night because they get enough light / nutrients during light hours? IDK! grasping at straws here. Either way it seems everything is growing like CRAZY and coloring up beautifully, even better this month than ever before, I am super happy with my tank. Ill keep this updated if anything changes but so far the no polyp extension at night is going to stay a mystery for me.

My lights clicked off 1.5 hours ago, and ill describe what I see. First off a ton of bristle worms, more than last time I checked, I have never really worried about these guys but dang there is a lot. Since my wrasse has been gone a lot more copepod activity, as well as these weird looking trunks...almost looks like a conch "trunk" like of an elephant or ant eater trunk that is sticking just ever so slightly out of the rock holes (spotted two of these). I have never seen these before and it looked like they were hunting coepods, they were sitting very still then would strike and try and grab one really quick then go back to sitting still. Im a little worried what the heck are these guys? Anyone?

Acros are ALL full retracted. Every single one, including mille's and my lokani. Anyone have any ideas based on my novel above?

Ha, my idea is don't worry about it since your corals are growing like crazy and have good color. Same situation for me. I'm not worried.
 
Yep im just going to adopt the mentality about this one that dont worry be happy, things are growing and doing well, so i shouldnt question it too much.

Sounds like a plan there, if they look good and are growing, just go with it.
Since some of mine do same thing at night, I'll take your advice.
