Small Boil/lump On Side Of Tetra

Hi guys,

I'm new to the forums and decided to join up after reading lots of useful info here.

About a month ago I discovered that one of my Black Neons has a small bump/pimple-like protrusion on it's left side. It is relatively small, but it looks to be a lump that is originating from inside, and is underneath scales.

Any thoughts on what this might be and if there is anything I can do to help would be much appreciated, thanks
I have included some (poor quality) images to get a better idea.

Aside from this bump, the fish appears to be behaving completely normally with no other side effects. The bump also doesn't appear to be getting any worse.

Ammonia - 0
Nitrite - 0
Nitrate - 15 - 20ppm

Thanks for your help

Does anyone have any thoughts on what this might be?

Can you get clearer photos?

I can do my best. Was only using the camera on my blackberry, but I'll try to get a better picture.

Hi guys.

I've managed to take a better picture of the problem. Hopefully this will give a clearer idea as to what it might be.

Thanks,
Will.

I'm really hoping that someone might have some idea as to what this might be?? The last thing I want is for it to burst and infect the other fish that I have in the tanks.

Thanks,
Will.

Bump

I have no idea; from the photo what I am assuming to be a bump just looks like a bit of shine on the "neon" stripe. I'm replying to give you a bump up the list as you've been waiting a while to find out what it is.

Bump - Still haven't worked this one out.

It is a definite protrusion from the side of the fish. Like half of a tiny ball pushing out from the inside.

Again, the fish appears to be in no distress and is eating and socialising with the other fish well.
