Sick file fish

[COCOBBALL]

I noticed my file fish who is usually very active juat hanging out on bottom not moving much.

When i got home from Thanksgiving he was alive but stuck to my overflow box.

I removed him and he looks like this now. Ive had him for over 6 months and no new fish additions.

I forgot i did add a Dragonnet goby about a week ago but hes alive and well

Was he eating? Dragonets have thick slime coats and can hide sickness very well. Closely inspect other livestock for external parasites.

He was eating strong always the first one for the food.
Yesterday he stopped eating and just sat on bottom of tank though.
Havent seen anything on my other fish yet but i will closely watch them for any signs.
