Why would one single Goni start melting?

[Reef Puncher]

Only one of my Goni is doing bad. I can’t figure it out. What would cause one to bad? Could the green Goni be killing it out of nowhere? They lived together for months. Only last few days he’s been melting. In image it’s pink one in back

Gonis are very, very picky. What works for one wont always work for others. How long have you had it in the tank? If it's new, it's probably not happy in its spot (light and flow), if it's been happy for a few months, read this thread.

Also, assure there are no pests. Even a fish could be pecking at it and cause it to melt. CUC are other things that may itritate/pick at it. Maybe set up a camera and watch before doing anything else.

i have bristleworms and aiptasia, bristleworms only come out at night and they are tiny. i dont think they are the problem...could be aiptasia maybe? i dunno. it was happy for 8 months. dont know why its randomly doing bad. i just sent off for another ICP. my last ICP 4 weeks ago shows my manganese was fine. i dose trace elements.

Hello,

I had a similiar issue with my pink goni verses my blue.

I did several water changes back to back and it appears that abrupt change messed up the pink but not the blue.

They are different subspecies of goni I cant recall the name of the one thats known picky but thats likely the issue

If there's one thing I learned over the years is every individual animal can potentially have it's own prefferences.
