They’ve had a few days rest so worth a try I guess.

So, just completed the course of Protozin and no improvements.

It seems whatever it is is still spreading as there are more fish with mouth issues appearing now.

I really have no idea what to do :(

There's something going on with the tank - are they all getting the mouth rot or are there different symptoms?
I have a nasty suspicion that whatever virus or bacteria it is it's a tough strain.
I'd be tempted to give all the fish a salt bath (use Marine salt) for 20 mins and see what happens.
Don't put salt in the tank, the shrimp definitely won't like that.

How many fish do you have left? You could consult a fish specialist vet?
Small tank - 125L - 3 Iriatherina werneri, 4 Celestichthys erythromicron
Big tank - ~500L - 1 Mastacembelus erythrotaenia, 16 mixed rainbows (Melanotaenia herbertaxelrodi, Melanotaenia trifasciata, Melanotaenia boesemani)

Hi @plankton

It seems to start in the mouth regardless, as white swellings around the lips. Then it moves slowly backwards along the body, and also seems to cause swim bladder issues.

The only fish that have visible body lesions are the red eyes, all the others just seem to have the slow progression mouth problems. The cory’s and BN still don’t seem to be affected at all, and the shrimp are fine.

Cheers,
Chris.

There are 4 Serpae, 3 rosy’s, 8 red eye, 9 city’s and a BN left. Plus around 20 amanos.

I think vet might be the next step if I can find one! Or try the salt baths suggested by @plankton as a last resort.

Cheers,
Chris.

Have you got pics of all the affected fish?
It may be best to take drastic action if they are too badly affected. (Sorry) :(

Hi @plankton

It’s becoming really hard to get pics of the affected fish now as they are hiding behind plants at the back of the tank.

I would say that all of the red eyes have visible lesions on body or mouth fungus, 2-3 out of 4 serpae have mouth fungus, and 2 of the rosy’s have mouth fungus.

I haven’t seen the plec in a few days (he spends most his time hiding under the wood), and the cory’s still don’t seem to be affected.

Here are some pics of the ones I could spot.

You need a strong fungal med by the looks.
Are you going to try the Myxazin?
If not, it may be time to think about euthanizing the affected fish. :(
