What is happening to my Acros?

This is the 2nd time this week that this has happened to one of my Acros and I have no clue what it is?? I went to work at 7am this morning and everything was fine, I then came back home at 12 and it was like this.. What is happening?

RTN Rapid Tissue Necrosis.
It is dying, well pretty much dead.
What are your water parameters like?

I don't see any flatworms in the pic but that is one possibility. The other common culprit would be alkalinity. What is your alk now and what was it most recently?

Agreed. You either have a pest or you've got some water quality issues.

The best part of having acros is , if they are ill and not doing well for a long period they may visually look "ok" but then just let go all at once.

So it could most anything.

I lost a pink birdsnest "overnight", turns out it had been a lack of flow in that spot.

Most of the time it is a big alk difference or high nutrient low alk. Granted I did see sea spiders do that to a customers acro one time. It was pretty crazy.

How long has the tank been up and running? Is there a chiller on the tank?

I've been super busy with work and haven't checked parameters in about a week but have been doing water changes and dosing no pox daily but today I'm doing everything.. all my other corals are perfectly fine and so are my 3 RBTA along with my clam but I'll post parameters when I take them here in a bit
