VirusAcro · Aug 1, 2014

This is not my image but some of my corals acting exactly like the image,is that like some kind of stress mode or something,it has been going on for a few months now,can someone tell how to stop it from acting like that or why is it acting like that..??.Thank you..!!!

is it close to another coral? that looks like a real estate war response..

VirusAcro · Aug 1, 2014

No it's about 3/4 inches away

Looks like the tissue. Its possibly bleaching out.

a pic of your actual coral would really help.. but the photo above looks like it's trying to fight to me.. notice on the bottom left polyp that cluster of white strings that looks like a ball of intestines? that's what they send out to fight other corals (they actually digest them)...

Looks like snoot from a vermidt snail. did it happen right after feeding. fallow the strings and see if it is coming from what looks like a tiny volcano

Maybe some kind of hydroid?

Ghill it is exactly like the images

Sirreal..the string shoot out before and after feeding

Those are the mesenterial filaments: polyp guts. Used for feeding or defense.

If your only seeing it when feeding, then it's a feeding response. I have had colonies that also do this.

bingo.. couldn't remember the name but that's what I was referring to.

Looks like a feeding responds to me.

BTW, 3/4 of an inch is very close. SPS can, "smell" each other at close range and if they detect another coral nearby it will slow down their growth and can enact aggressive responses.
