• Identify the fish, season, water conditions, and behavior involved.
• Provide space and clean, oxygenated water instead of assuming a single trigger explains the event.
• Separate injured fish or seek advice when spawning behavior becomes harmful or abnormal.

When should I ask for help?

Ask for help when the situation is severe, affects several fish, involves a possible toxin or injury, keeps worsening, or cannot be explained by the available observations and tests. Keep notes and product labels available.
