AEFW from DD

[Thales]

I didn’t count the moving pests. I noticed a few and didn’t think it would be necessary to count them especially since the picture is from my tank water dip and not the coralrx.
When I took the picture I wasn’t sure what to think. I noticed movement but wasn’t really sure if there was slight water movement that tricked me into believing something was moving. That’s why I waited overnight to recheck the water and look for a fish or invert attacking it. The coral was going downhill but I was trying not to panic and do something drastic that would kill it. I know there are multiple acro pests and honestly wasn’t totally convinced that they were my only problem at the time. The coral’s tissue loss slowed after moving it around in bucketed tank water but it still continued. That and no signs of invert or fish abuse is what made me think they were my problem. So I dipped all of my acros, fragged the tips of the dying colony, and quarantined everything.
I didn’t move faster because originally I thought it was a snail, I had to mix up my salt, get the quarantine set up properly, and I never imagined it would die by the 3rd day. I used my existing tank water for my quarantine tank and made sure everything was stable with it. I added acropower and a vitamin supplement to the quarantine with hopes it would save what I fragged.
milk attach a crappy picture and you can get an idea of what was going on.

Gotcha thanks. That pic doesn't look like AEFW damage, impact, or bite marks. Combine with the other pics and what you have told us, and I would say that this wasn't AEFW. Could be some kind of RTN/STN or ADR (ain't doing right) - sometimes corals just suck at life.

That looks like RTN to me, not the loss from AEFW.

What normally causes something like this to occur? This is the first time this has happened to me. It appeared very healthy up to this point and parameters are stable. I’ve dealt mainly with moderate sps and most of my acro experience is from years ago. 6 years ago my job took me away from home for a week to two weeks at a time, and I wasn’t able to adequately care for them and got rid of them. Only had a bonsai colony and a couple of echinata colonies. I changed salts from reef crystals to Red Sea coral pro but had only changed out 10% of my water 4 days prior. I’m a stickler for water parameters so I know I didn’t throw anything off and verified it was mixed well. My alkalinity runs around 11dkh and with my oversized skimmer and ats I’m low nutrient, but I try to feed well and dose aminos.

We don't know. Sometimes corals just suck at life out of the blue.

I guess I just need to be ready to accept that I’m either getting a good coral or I’m lighting my money on fire and watching it slowly burn while my wife complains(didn’t want me to set my tank back up after all of the problems) and tells me I told you so and we could’ve done this with that money.
