polyps closed?

[FishNDip]

Usually don't ask these questions because it's so hard to find the cause of why your polyps have closed, but here's the deal if anyone can help.

Got two types of colorful polpys on a rock. Ones bam bam, and the other is a green type I'm unsure of. The green polyps all of a sudden just closed up 3 days ago at the same time. The bam bams on the other hand are open looking good. (there's about 10 of each coral type) I tested the water and nitrates and ammonia are undetectable by my API tester. I don't think something is eating them because they all closed up the same time, and the bam bams aren't closed. The tank is fishless. Algae isn't covering them. Only thing I can think of is the mushroom coral was shedding and "maybe" letting some toxins in the water, but I threw carbon in a day ago and nothing changed. ?????? :sad2:

Do you have any other corals behaving weirdly?


I have a variety of corals all over, and there seems to be no rhyme or reason to why one all of a sudden decides its unhappy and 'closes up'.

The only one I trust as a sign something is wrong is my Elegance. Its usually the most sensitive coral and will wilt first if something is amiss.

Yeah that's the weird thing. I have bam bams, msuhroom coral and GPS which are all looking healthy.

One thing to note is polyps like a little nitrate in the water. Also, not all polyps like the same thing. Some like more light, some like less, some like more flow, some like less, etc. So just with one variety doing well does not mean another next to it will do the same. They also just close up sometimes for bit then reopen as if nothing happened.

I hope they just decide to open up soon! :worried2: Silly polyps closing up and scaring me for no apparent reason. If they want to die, then go ahead. :blown:
