He’s also stopped swimming around actively, though he’s still eating normally.

Also added the tank parameters as screenshot.

Chemistry looks good.

Nip marks? A disagreement.
Have anyone else?
 
Nope, he is the only fish in the tank currently. There are 2 cleaner shrimps and snails.

This is a gash injury which should heal on its own but watch for redness which would require treatment in separate tank using seachem neoplex

Welcome to Reef2Reef!

How long have you had this fish?
Can you post a video of it?

Thanks! I have the fish for 5 years now.
It seems to get worse. Stopped eating. Keeps lying on the side with the spots. When I get the opportunity, I’ll post a second video of the spots.

That’s a serious issue - rapid breathing, skin lesions and not eating all point to a systemic internal infection. One of those is fish tuberculosis - common in long term captive fish, it unfortunately, isn’t treatable.

Water quality looks good, but 10 ppm dissolved oxygen is way above saturation, so that test is an error of some sort.

😢 I really hope this isn’t the case. Everything I’m reading about fish tuberculosis is pretty alarming. From what I understand, it sounds like I may need to completely restart my tank? 😳

This is the test chart I used. I can redo the test if needed, but I don’t think it will change the results much.

Mycobacterium marinum - fish TB is found in virtually every aquarium. It is found in tap water and frozen fish foods. What happens is with older fish, they lose the ability to fight off these bacteria and a long term chronic infection sets in. You won’t need to reset your tank.
