Red Cloud Mountain Minnow problem?

[Chickadee]

One of our fish has got what looks like a white bubble on his nose!
It doesn't interfere with eating and it seems okay apart from that.
Does anyone know what it could be?

Red??? Cloud Mountain Minnow?

[Schutzengel]

White cloud mountain minnows. It could be a type of fungus. You need a fungus cure liquid to add to the tank, which you can obtain from an aquaria shop or a good pet shop. Have you got the fish in a tropical tank, or in a cold water tank. They will live happily in either, but are more susceptible to fungus in a tropical tank especially if you have recently added new fish. The tank needs to be treated as if it is fungus it could quickly spread to the rest of your fish. Good luck.

How did that happen? I wasn't finished yet and the page disappeared.

It could be a myriad of things but is likely to be a fungi as a secondary symptom of an injury. If it looks a bit 'hairy' close up get a proper cure from an aquarium shop or pet shop that you know to be knowledgeable about tropical fish.
