does anyone here have experience with sick blastos?

[SeeCrabRun]

I bought a colony of blastomussa wellsi last Saturday. When I got home and dipped them in coralRx I noticed one polyp had some tissue damage. Almost seemed like the hard spike of the skeleton under it poked a hole in the tissue.

Slowly over the next couple of days that polyp lost more and more tissue from the center out. Now it has a little rim of tissue toward the top and another bit toward the bottom, but the middle and sides are gone.

Now, the sides that are gone have a layer of white fungus/mold/too that has formed and it is starting to encroach on the polyps next to it and they are starting to show signs of tissue damage where they touch the dying/dead one.

I'm very new to coral keeping and so I'm at a loss what this is or how to treat it.

I did spot feed them all last night with some cyclopeeze and the 2 sick polyps did eat some, but didn't blow up around it like the others and seemed to just be very weak for the whole process.

I'm hoping to save the sick ones, but if nothing else, keep it from spreading to the rest of the colony.

Can anyone help?

The first picture is today, second is a couple days ago, third and fourth is when I noticed the tissue damage.

The damage seems to be mainly restricted to the one polyp. I wouldn't worry about it and just make sure to keep the colony in low-med flow and concentrate your efforts on feeding the healthy polyps since they all share the wealth. You should try feeding frozen mysis too.

It's not just the one. The two next to it are showing skeleton at the border to the one that is dying.

I've been offering everything I have from mysis, to plankton, to pods, to LRS nano reef frenzy and the cyclopeeze. They only just took anything laaaate last night and was the cyclopeeze.

I was researching ways to treat sick blastos and saw they may not become active for feedings until the night. It was 1am and I saw some movement so I tried and everyone but the dying one took some. But the 2 bordering ones has to be fed multiple times before they finally took some and even then they struggled getting it in their mouth and keeping their mouth closed.

I would do a lugols dip, then set it in an area of gentle flow to prevent bacterial infection/ brown jelly.

Thank you. The response from the store was similar.

I would advise a lugol's dip to help heal the the coral and place it in a spot in the aquarium where it isn't receiving a lot of light or flow.
Also you can add trace elements (seachem reef trace & brightwell vitamin C) to the aquarium to help the healing process.

Should I do the additives as well?
