oily eyes on puffer fish

[Tctran]

HI everyone.

Been dealing with all kinds of issues with my tank. Have lost 2 lookdowns, 2 lionfish, and a yellow blotch rabbitfish.

My puffer is very healthy and eating well. I do notice he has oily eyes, not clear. Any thoughts on disease and treatment please?

thx.

Completely normal. Puffers eyes naturally have an oily appearance. In the wild they hunt at night.
