Neon tetra dying?

[hils]

Not the best picture, but this neon had a strange pale patch, almost a thickening on the base of his tail.
It's still eating etc, but a bit quiet.
Saveable? Or time for euthanasia?

Sounds like neon tetra disease to me. I'd euthanize.

+1 I had a neon die from NTD and it looked like yours does. Better to euthanize one fish than risk the entire tank.

Will get rid. I've only got two left. Started with 10 last year. Poor things. :-(

 

[Anders247]

Sorry about your fish.

Or bacterial. Either way keep an eye on the rest of your fish.

I fear when people say NTD.
It has no recognisable symtptoms that are different from other parasites.
NTD is highly contagious and un curable so IMO this is HIGHLY IMPROBABLE.

Fish with NTD often have a pale patch in their fish.
Even if this isn't it, it could be columnaris which is pretty bad, too.....

So basically kill the fish and hope my other species don't get it?

Or just quarantine it and monitor the health of your other fish to see if they develop symptoms. If it is columnaris it won't take long for symptoms to develop.

It is not so much hope.
I do believe it could be columnaris that has at least 4 different strains.
The skin issues can be cured with antibiotics(kannamyacin I believe?).
Sometimes salt and LOWER temps.(yea DO NOT raise temp!).
It is the internal strain that kills quickly and is most difficult to treat.
If the fish is too far gone(looked treatable in pic IMO) then euthanize(done it many times).
You still need to treat the tank either way.
Time to play DR!
Best link on columnaris!

Read it!
All this is to help and purely from my own imagination(maybe not?)!

I've only seen the white patches with later spine curvature once or twice. At the time I thought bacterial as also had tail lesions like pic plus cotton mouth and saddleback on others. I'd imagine you could be unlucky to have both... (That's a cheery thought!).

Either way QT straight away imo. If you assume bacterial you could then try some treatment methods. Actually I guess you could try treating for both internal parasites and bacterial. That might be a bit expensive so other reason for QT. There's no reason they can't be treated - I would guess it is due to the size of the fish and that by the time it is spotted it is generally too late.

A steady loss of these fish I've found to be environment in part imo. I don't mean a bad tank or anything, just they are under a bit of stress, get a bit more stresses and thus open to any infection. I tried them three times and have given up.

Some articles I have.
