White bits on Neon Tetra tail and fins

[Amanda Ayling]

Two of my neons have white on their tail and fins, it doesn't appear to have passed onto any other fish in the tank. They aren't distressed but can someone please tell me what it is and how best to treat them. Seems to be just those two fish. Many thanks

Hi and welcome to the forum

Can you post a picture of the fish?
Set your camera's resolution to its lowest setting so the images are small enough to fit on here, and take some pictures of the fish. Check them on your computer and post a couple that clearly show the problem. Remember to increase the camera's resolution afterwards or all the pictures taken will be smaller.

How long has the tank been set up for?
How often do you do water changes and how much water do you change?
How often do you clean the filter and how do you clean it?

I have had a few neons do that in the past but can’t tell you why. It didn’t seem to hurt them though. Tried different things but didn’t go away. Perhaps if you can get a pic Colin can help figure out what it is. Good luck!
