I bought a Solarensis Wrasse from my LFS a little over a week ago. Everything was fine for a week. He ate like a pig, very active, no aggression from tank mates.
When the light came on a couple days ago it was clear something was wrong. He was swimming weird. He would stand straight up and then slowly fall backwards. Swim sideways, and sometimes upside down. It's like he's lost all equilibrium. I caught him easily and put him in a hospital tank, but I don't have a clue how to treat him.
I did a google search and nearly all results talked about a swim bladder problem but they were talking about fresh water fish.
If anyone has any expertise in this area I'd love to hear it. I hate watching him swim like that.
