Is this STN?

Hope for the best, watch your other acropora like a hawk. Definitely pitch that piece like Seadweller said, not worth it.

This is a great article that shows you what to look out for and how to treat.

To lighten the mood a bit, this always cracks me up.

Good stuff.

Oh boy. Definitely toss the piece, unless you are set up for a few months of quarantine and dipping.

Ya I don’t have the means to set up a separate tank to qt it. Going to use the old pull and pray method on this one.

OP this is actually a very valuable lesson for you. The good news is you don’t have a full tank of thriving acros that could get wiped out. I would pull your wd and slimmer out and look at them with some magnification and look for worms or eggs, dip them in Bayer advanced, rinse and then put them back in the tank. I know there is a typical hatch cycle with these little bast@rds but I’m not sure what the time frame is. You’ll want to repeat the dip cycle several times before you even think about acquiring more acros.

Ya I’m glad I’m learning now rather than later with more in my tank. I have some Bayer, I’m going to mount the others on plugs som I can pull in and out easy to dip.

Hopefully we can get a better protocol from someone that has been through this.

Maybe taking a read though the sticky thread might be of value to the OP?

With AEFW’s I’ve always been extreme in my qt system and past frag tanks. 3 years ago they found their way into my main DT I literally threw corals in the trash anything that had lots of eggs/worms it was for the greater good. A lot of my older acro’s I still currently have survived the flatworms. After the initial “cleansing” and inspection of every acro colony, nub, and frag. I removed anything like bases/existing frag plug remounting the majority of them. Anything that passed visual inspection was dipped in Bayer then revive serveral times a few days apart for
a few weeks. I always basted the heck to knock off everything I could angled tweezer were helpful dig stuff out and scrape the eggs. The majority of Infected corals got chopped and same dipping procedure Bayer->revive in high concentrations and more treatments. For the most part I dip all of these one at a time decrease risk, and to see which corals I needed to focus on. AEFW take patience along with time.

Once things slowed down I could see light at the end of the tunnel I started blasting my acros with a maxi jet twice a week. I always had a lot of wrasses. I used zeovit flatworm stop and coral Booster for 1.5 years. I started dipping all my incoming corals extremely hard religiously still not fool proof though. I later got black bugs a year later that’s a another story. The damage I always observed the skeleton and the tissue line for flat worms doesn’t general turn as green, there’s eggs, and with stn the line is pretty linear you can see a line of recession in the tissue (depending how progressive it peels) vs. aefw’s ranges for patchy to irregular. These are just a small of my bad quality reference photo’s from my recent battle with stn.

The fox flame after it started to grow back.
