I have a silver bellied coris wrasse that I introduced into the tank about 2 weeks ago. For the past day or so it has been swimming at the surface of the water in flow. I don’t think this is normal for wrasses, and I would appreciate any feedback on what anyone thinks this is. I added a blend to the tank yesterday but I thought it had either flukes or inch so I took it out this morning. Do you think it caught something?
