Mccoskers flasher - strange behavior

[ksfulk]

I came downstairs a little bit earlier than normal to check on the tank and I caught this little guy parked against one of the rocks in stressed coloring and breathing heavily.

I've had no issues with disease in this tank, and all the inhabitant have been through CP, prazi and observation. No new fish or inverts have been added since June (corals only, no plugs). I don't see any telltale issues (red splotches, white bumps, cloudy eyes, etc), so I'm thinking it could be an aggression issue maybe?

There are no other flashers in the tank. There are two leopards ( standard leopard and ornate leopard), and three fairies (cf cyanopleura, rubreus, exquistius) but no observed issues between them and the flasher. There are a number of other fish (five anthias, kole tang, sailfin tang, occellaris, twinspot blenny) but no observed aggression. No one was picking on him while I was observing. I've moved the wrasse to a hospital tank, but it's unable to maintain orientation even while resting, so my assumption is he is done for.

Any thoughts on things to look out for in the DT for potential root cause?

Yeah that doesn't look good for the Mccosker.
He might got spooked and did the jumpy thing as result he crack his head or something.
Keep a eye out just in case as you mentioned you added some corals but without the plug but still you can bring over a bug of something.
Sorry to see your McCosker suffering.

Could have been. I'm fairly certain that the systems the added corals came from are fish free but I could be wrong.

I've seen the fairys hit the water line when they get the evening friskys but this guy isn't a part of that. For now I'll continue observation, but I doubt he'll make it through the evening.

I just want to point out that any coral with a hard surface (even leather corals have skeletal needles for absorbing calcium) can "host" the tomont stage of fish parasites.

Unfortunately, I can't tell if your wrasse has a disease or just trauma of some sort. If he dies, drop the body in FW to check for flukes.
