We got some new corals in 3 days ago and we’re now having some issues. Yesterday morning one of the new corals was half covered in a white stringy web-looking thing that was kind of flapping in the flow. I blew it off, only to find the coral below was bleached in that spot.
Very back middle; poor picture but you can see the far edge is bleached and the rest looks fine. (Ignore the white acro, it arrived that way) The only nearby coral potentially aggressive was a chalice at the time but they weren’t actually touching on the frag rack. Not sure what kind of coral it is; it was a bonus one. Small hairy polyps with yellow spots.
Well this morning on the complete opposite end of the coral rack from where that one originally was, my new acan was covered in what looked like a thick mucous; both polyps, and it looked like the coral itself produced it. Completely covered the polyps from side to side, not overflowing them, just right across the tops.
Unfortunately didn’t get a picture of the mucous itself, but this is what the coral looked like after I blew it off; bleached underneath with most of the red color loss. Keep in mind all day yesterday I was around this coral and it looked perfect with beautiful coloring, open polyps, etc. Now overnight half dead with mucous on it.
I don’t think it’s close enough to anything super aggressive that it would be warfare. The other acan has really short tentacles and besides, this mucous or web or whatever yesterday was on a different coral on a different side of the rack. So any ideas what’s killing my corals?!
