Hi,

Noticed this small white spot sticking out the side of a fish today. He's acting totally fine.

Any idea what it could be?
Hoping it's just a little nip from another fish as he has had a little nip on a scale there previously.

From that angle, looks more like a disease.

Cleared up pretty quick. Thinking it might have been him scraping against a rock and the white spot may have been a single grain of sand wedged in a damaged scale. Odd I know, but the only thing I can think of that would have led to it dissapearing overnight
