Fish looks thin and moribund. I dont as Jay also indicated see anything that can be done to restore its energy and likely as much as I hate to say continue to decline. Sorry to see this
@Jay Hemdal can you view the video on a large screen? On my computer screen I can see the wrasse has a cloudy eye and looks to be missing scales and has some deterioration on the caudal peduncle. We thought it looked diseased and underweight in the wrasse thread, but didn't know what the ailment is in case the OP needs to treat his other fish
