Crazy PE or something bad going on?

[ojonas81]

Lately I have noticed that two of my SPS have gotten crazy PE (at least that is what I think it is). It happens random but they both usually at the same time. When the photos below were taken it was just after a WC. Is it just PE or should I be worried about something?

Thats not PE. Not sure what it is mine do that from time to time. My guess is its pooping/peeing or releasing sperm. But I don't really know.

Sweeper tenticals , it's doing that to protect its area.

One of my acros has been doing this lately too. And its been dying back in the spots where the tenticles appear... sorry i cant say whats going on either but also very curious

Personally ive never seen any of mine do that.

have you checked your alk lately?

A few of mine do this daily when I feed the tank. That brs reef Chilli really makes it happen

Anytime I see this out of my acros it's usually a sign there is something not quite right with my water condition.

I think it's feeding, it happens when I feed the fish.

I saw my strawberry shortcake do this once when i put it in the tank. At the time i tought it was to get rid of some irritation from me toughing the coral.

Thanks everyone. My alk and Ca have been stable for a long time. Alk is always around 8.7 to 9 and Ca hoover around 430.

I usually see this after feeding, especially when feeding includes coral specific food. I ha e many SPS in the tank but these two are the only ones doing this.

Mesenterial Filaments: Used for both defense and as a digestive mechanism.

Your corals look hungry to me based on the coloration and such a strong presence of the filaments. Not uncommon to see mesenterial as a feeding response after the introduction of food.

Are you feeding the Acro's and if so what?

 

[ojonas81]

Lost some coloration after a tank move that was done about a month ago.

Feeding the corals (both spot and broadcast) a mix of Phytoplankton, oyster feed, zooplankton etc. a couple of times a week.

As he said. I've only ever seen them on my acros after I feed. Its always seemed to be a good thing in my case. I feed oyster feast, golden pearls, cyclopeeze, ova, rods food.
