White mouth???

[Deathstar31]

What is this on my cherry barb? I feel like I notice it a good bit when the water is just cleaned. I did just recently clean the tank, so please excuse the mirky water. Thanks.

An image that’s sharply focused would help and one taken from directly in front as well.

I can just make out the white but unfortunately, I can’t see any details.

There are two fairly common things it might be - one is fungus, which is very easily treated & cured.

The other is columnaris - a bacterial infection that has a sky high mortality rate, but the one good thing about it is that in this presentation, it’s more likely to be curable than any other of the forms this disease can present.

Treatment for very early columnaris in the mouth area can be the same as for fungus but if it isn’t effective the only treatment that might help would be antibiotics added to the food and ingested by the fish.

Do you have or can you quickly get Methylene Blue?

The fish should be quarantined.

Would a 2.5 work as a quarantine tank? How long do I quarantine? What medicine would you recommend? No I don't have Methylene Blue, I don't think. Thanks.

I’d start with Methylene blue if you can get it quickly. The 2.5 can serve as a QT.
