My mccoskers wrasse is acting very strange. I am very worried. I thought he was dead because he was just laying motionless and he then swam and started doing this. He is now laying again motionless. What should I do?
 
Unknown neurological wrasse disease is the likely culprit. You can search the threads here and read up on it.
 
Okay will do thank you
Hopefully it’s not, and it’s just stuck on stupid, but most likely UNWD. Affects that type of wrasse a lot, same as Coris wrasse. Some think it’s the collection method, @Jay Hemdal did a lengthy post about it.

Opposed to UNWD, it appears fish is thin and moribund. The current seems a little strong within this tank also. With UNWD, fish swims tail down or swims with a bent spine and despite all this, the wrasse will still attempt to feed and display no damage such as crashing into objects.

It doesn’t look quite like UNWD - the key symptom with that is that despite the weird swimming. If your fish isn’t trying to feed, then something else is wrong with it.

Here is my post about it:

I found the cause I believe. Ammonia is at 1.5. Everything was okay a few days ago. Poor guy is feel so bad. He isn't going to make it. I tool everyone else out and put them in a fresh batch of saltwater matched in temp and salinity.
