Help with Acans please

[Rukk]

Need help... One of my acans seems to be succumbing to some dark mushy looking little stringy kinda snotty looking stuff. Its the one on the left and its probably gone and it appears that it is spreading to my other acan which has been growing pretty good.

The stuff is all over the one on the left and especially around the edges. And it looks like it is on the bottom of the one on the right now.

Hardly have any algae in the tank, grows on the scrubber like a champ tho.

Any help or advice would be appreciated.

Look up brown jelly disease and see if that's it

How long have you had them? Any changes in light/flow/placement? Any chance the torch in the back is putting out long stinging tentacles you are not seeing? Ive seen mine reach out quite far on occasion and kill an acan when I didn't move it fast enough.

I would dip the coral in a iodine type dip.

Thanks for the responses, I've tried the iodine dip, we'll see if that helps...……...
