Blue chrome has bubble on eye

[Perthegallon]

My blue chrome does not look to be doing good as it has a weird glass looking bubble around it’s one eye completely clear? What is this and why do I do?

That is a gas bubble, usually caused by mechanical damage. Catching the fish in a net (and them shaking around) can cause it. There isn't really any treatment for this if that is what caused it - some fish get better, some lose their eye and some die.

If you see it in both eyes, or in more than one fish, it could also be supersaturation. That is caused by an air leak on the suction side of a pump and can kill fish very quickly.

Here is a link to an article I wrote about eye issues:

Aquarium Fish: The ‘Eyes’ Have it: A Review of Eye Health in Aquarium Fishes

Aquarists need to inspect their fish closely every day, for signs of impending health problems. It is much easier to resolve a problem when it first starts, than to attempt a drastic emergency treatment when the fish is close to dying.

well no one has touched him in over a year so I think it is a bacterial infection? I started him on bacterial infection meds and moved him over to a calm qt tank and it has deflated on the one eye while the other eye is okay

Unlikely to be a bacterial infection, I didn’t see any sign of inflammation. Be careful with supersaturation, it is still a possibility. The gas bubbles can pop with handling but very often reinflate in a day or two.
