🚨 Emergency Symptoms

🫧emergency

Dropsy (Pinecone Scales)

Dropsy causes fluid to accumulate under the skin, making scales protrude outward like a pinecone. It is a symptom of organ failure (usually kidneys) rather than a disease itself. Prognosis is poor.

⚠️ Urgent Symptoms

White Spots (Ich)

Ichthyophthirius (Ich/White Spot Disease) is the most common fish disease. Small white dots appear on fins and body, resembling grains of salt. Highly contagious and fatal if untreated.

🩹urgent

Fin rot causes fins to appear ragged, frayed, or discolored. It progresses from the edges inward and can reach the body if left untreated. Caused by bacterial infection, usually triggered by poor water quality.
