Thanks for the advice. I treated him once, but the bubble has come back,
however. How often should I repeat this treatment? What can I look into
that might be causing this? Or should I just keep lancing and treating with
the peroxide until it stops?

Thanks,

Devin

it sounds like henneguya, put fish in separate bowl, lance it, dip it in
peroxide (1
part 3% drug store hydrogen peroxide to 9 parts water, dip for 10 SECONDS
only).
then put it in quarantine so dont give it to other fish.
1/2 cup peroxide + 4 1/2 cup water in a bowl if that will cover the fish.

I have a large Oranda (at least I think he is, large orange head). He
has
what looks like a blister on the inside of one of his gills. It's
swollen
on the inside, and a bubble has formed that sticks out of the gill
cavity.
I see no signs of blood in it, and it looks totally clear inside.

Any idea what this is? Should I leave it, or try to lance it?

No other problems with the fish. I have 4 in a 40 gallon tank. All seem
healthy, happy, active, and eat well.

Thanks for any help,

Devin
