He was mostly just lethargic, but then he went upside down for a bit before ending up right side up under the sponge.
I was scheduled to do the final water change after the last dose of GC tonight, which I did.
His breathing is still heavy but it has definitely improved. His mouth is more open than normal too, which I forgot to mention previously. He came out and swam fairly normally for a bit too, but I am not optimistic yet.
It’s so weird...I’ve had many fairy wrasses over the years and this has never happened.
I’m not trying to wish anything bad on you but watch him carefully. Mouth being locked open is a sign of Uronema. I’m hoping it may be an injury but just watch him.
