Treat clamped fins as a symptom that requires careful observation rather than a diagnosis by itself.

White fluffy growth on fish or eggs is fungal — it attacks weakened tissue, not healthy scales on pristine water.

Bulging eyes signal fluid behind the orbit — identify whether one fish had a fight or the whole tank has water problems.

Fin rot starts at the edges — catch water quality problems early before infection reaches the body.

A practical guide to spotting, treating, and preventing ich — the classic white-spot disease that spreads quickly when fish are stressed.
