Neon Tetra fading

[oneeyedfrog]

Hi,

We have 6 neons in a 100l planted tank with 12 girl guppies and a bristlenose. I noticed today that one neons red line is a browny red not bright red like the rest it also looks as if its blue stripe is bent. It seems to be behaving normally.

Amon- 0 ,Nitrite 0, Nitrate 20 ( did water change),Ph 7.2 temp 23

I had just set up a QT ready for a new lot of neons as we were going to move the guppies out and have a neon only tank. Guess I won't be doing that for a while now.

If I can catch the little bugger I will move it to the QT. It hasn't slowed down at all.

Is there anything I can try to treat it with?

Is it likely to be neon tetra disease? These fish have been together for over 6 months and have not been fed live foods so how would it get it ?

Thanks for your advice

It could be old age or it could be Neon Tetra Disease

I would not treat a fish with anything unless I knew what I was treating it for.

A fading neon has several causes - stress, disease, mood or old age.

Usually stress is caused by water conditions. If it is only 1 fish though I would look to other reasons.

Disease is possible but hard to diagnose - especially in a neon. I doubt it is neon tetra disease

Neons will lighten and darken depending on mood or substrate. It may be being bullied.

If your neon is 5 years+ it is old age

Bent bits may be genetic and show up as a fish ages

If it is otherwise acting normally I would leave it alone but keep an eye on it.

Neons are prone to keeling over for no apparent reason, I prolly just keep and eye on them for a while.
