After looking at the tank today I've discovered 2 or 3 more tetras with the beginnings of that funny mouth , fungus/fluff, bulge.

They are all neon tetras, a couple of them have no red , whilst my cardinals are unaffected. Still treating with Esha but really have no idea what it could be but its definitely spreading through my neons the cordorys , ginger, gourami phantom , rummy nose and penguin tetres all seem unaffected, as do the baby mollles.

Am I treating with the right stuff or will all my neons get this? I can try to post some better pics but not sure how as the little buggers move so quick

For a minute I thought one of the penguins had it but realised he was busy eating one of the bottom feeder pellets and swimming aroudn with it stuck to his mouth.

From what you're saying it sounds like your Neonsmay possibly be infected with Neon Tetra Disease. The fungus/fin rot are secondary infections. If it is NTD, it is incurable and affected fish should be put to sleep. Have a look at this article and see if the description of symptoms matches what you are seeing. http://www.fishtanksandponds.co.uk/fi ... lth/neontetradisease.html

I was just about to reply and say I think it's neon tetra as one of them now has bumps on his body too.

How to I put them to sleep ?

You can use clove oil, available at any chemist. See this article for details: https://www.wisegeek.com/what-is-the-m ... y-to-euthanize-a-fish.htm

thanks. I have got 5 in the clove oil stage atm. The coupel of toerhs in the tank two have minor fin rot... should I do those too they show no sign of flufflylstuff or bent spine, after watching from above ... I'll do a 50% change tomororw and let the tank settle for a bit .

I would continue the treatment and give those others a chance as they may possibly not be infected. The protozoan that causes this is transmitted by fish eating the bodies of others that have died, so they could be OK.

ewwwww..... definitely no dead fish floating in my tank, or I've found . none floating at top or sunk on bottom so fingers crossed.

5 in total, gone via clove oil, then vodka

would it make sense to water change tomorrow, and then restart the treatment for 5 days?

Yes, I would do that. But if they don't improve after the 5-day course euthanasia would be best at that point.

the ones that have lost their red, shall I inlcude then in the euthanasia in 6 days if they don't recover?

Yes, whitening of the red area is a sign of the disease. Whilst colour may fade with other diseases, this should be addressed by the treatment with Esha 2000. If it isn't then you can conclude they also are infected, unfortunately.
