Lets talk polyp extension and coral health

[Seansea]

So I'm trying to figure out why some sps corals extend polyps and some dont in my tank. It appears it has nothing to do with the health of the coral. My meteor shower, emarld fire digitata, stylolciellnella, tropic thunder monti show no signs of polyp extension yet are growing at a very high rate. I dont believe if they were unhealthy they would grow like this. My stylophora has great polyp extension right near these and is growing great too. So what exactly causes some to extend some not too but yet appear very healthy and growing othewise?

Most likely a combination of things. I have the same issue in my tank, so with any luck I'll figure it out... someday.

Im starting to think its hunger that drives there polyps maybe. I dont know really but they dont look as cool without there polyps showing.

Following. I have the same thing going on and gave up trying to figure out why. I'm more concerned about the darn rtn that occurs randomly out of no where and usually the nicest frag in th tank

I am hesitant to say this but I cudda swore my corals had PE at/before fish feeding time….
As weird as it sounds, for brainless low life forms they seem to know…

oh they learn. Usually only takes about a few days for them to figure out the lighting schedule in my tank and start to ease into it. THe lps and softies looked closed then start to slowly open during ramp up and right before 100% blasting they open right on que. Pretty sure lighting and food is all they know tho
