Yellow wrasse with red gills and red eyes

[NanoRookie]

Hi, need some help, my yellow corris wrasse has red gills and red eyes, he has been hiding for a week he came out and its acting very strange bumping into everything and spinning. Took him out. All other fish are doing well.
Parameters seem fine. What can i do. I just took him out of the tank.

He could have internal parasites if it is a new fish I would try using kanaplex and Metroplex together to see if it doesn't help mix it with their food and feed it to him keep them in quarantine and just watch him
