What could possibly be wrong with my Cowfish?

[brittbritt115]

Hello, about 2 weeks ago, I purchased my first cowfish. So far, its been doing great (eating well and not stressed) this morning I woke up and noticed a cloudy white film growing on its nose and into its eye. I've checked my water multiple times and everything is coming back with a normal range. I'm trying to figure out what this could be? Please help

Any aggression going on with the clownfish? The caudal fin looks nipped.

Otherwise, @ReefSquad

Welcome to Reef2Reef!

Cowfish are rather delicate, they often don't thrive in typical aquariums. In this case, I'm looking at the tail damage - somebody in your tank has been going after it.

The cloudiness is extra mucus, possibly bacterial though, visually, you can't really tell the two apart. I think you'll need to isolate this fish - in a hospital tank with a good bio-filter and dose it with an antibiotic - Neoplex is one good choice.

I haven't noticed any aggression but just to be safe I will go ahead and move my clownfish to a different tank.
Thank you so much for the feedback!

These are fish that should not be sold in the hobby and this has been for years. 5% may survive for a period of time but often, they eat, then stop eating, become lethargic and then found on the sand bed deceased.
