First time Acro owner help needed!!!

Mille has these white spots I just noticed, nursing it back to health it was the sole survivor of 9 frags. It’s doing well color is back and polyps are extending. Shipping box got too hot. Are these flatworms I’ve got? Just noticed them… I’ve got a 6 line but he prefers copepods apparently or hasn’t noticed them

Heat kills.
As to AEFW, nearly impossible to see on the flesh and those small white spots aren't really indicative of anything specific.

To rule them out, a cheap dip of food grade potassium chloride, 1 tblspoon per gallon TANK water for 5-7 minutes will drop them dead so you can confirm. If you see worms, you will have to treat again weekly for 6 weeks. The eggs are unaffected by ANY dips.

Best I can do for pics… potassium chloride? Easy tank dose solution!

That appears to be exposed skeleton but doesn’t really look like AEFW bites. Probably just a little shipping related tissue loss on an otherwise healthy coral. At first I thought it might be mesenterial filaments, which are another common response to thermal stress but those spots don’t look like them. A potassium dip is a very reasonable idea (I dip all of my new corals in Reef Primer which is potassium based) and not particularly stressful for your coral.

If this is a sole survivor of a high temperature incident, you’ve probably accidentally selected for a thermally resistant strain of A. millepora. Thermally resistant strains tend to be much hardier than non-thermally resistant varieties, so this guy is probably a great starter coral.

I don't think he meant dose KCl directly to your tank.
That was the recipe for a dip in a separate container.

Would’ve learned real quick

It’s doing great compared to the rest, for sure resistant… hot air came out of the box when I opened it… first thought was “boy, box full of hot air” then I saw 2 bleached. “The rest will be alright…” the others still had flesh but as soon as they were in the tank it just blew away I’ve ordered before from this vendor and it came in good but I don’t know what the heck happened to my acros. Texas weather is all I gotta say… thanks for your response sheds some insight on why it’s the sole survivor
