Tiger Oscar mouth problem

[byron]

Hey, I have this tiger oscar whose about 2 inches long and there is something wrong with its mouth. His mouth is always open but everything else is fine. He is eating fine and water condition is good. I did some research about it and people said it might have dislocated its mouth. Do you guys have any knowledge of this issue?

one of my oscars ate a otto cat when he was smaller and his mouth stayed open like you described for about 4 days then went back to normal or close to normal anyway.

My guy use to do that when he wuz about 2 inch in his 5 gallon... found out later he wuz depleting of oxygen! That wuz when I was still pretty new to the hobby... upgraded my tank and he's still alive now!

it looks like the skin/slime is also coming off. Check your water parameter. Dislocating jaw can be fixed as soon as it happens. If left along for a while, it will stay that way. Though from the photo, it doesn't look like it is dislcating at all.

i wasnt too sure what it was but he has been gone for awhile now.

salt + water change will be help!

SO the main reason to this problem may be the cause of the water condition? So if I do a water change, the problem can be cured?
