Feeding Koi in Florida's Unpredictable Winter Temperatures

Activity-Based Feeding

Florida's swings (80°F → 39°F in 48 hrs) make calendar-based feeding dangerous. Instead, feed based on fish behavior.

The Rule

• Active, mid-water swimming, begging: Feed normal summer ration.
• Bottom-hugging, sluggish, ignoring food: Stop feeding entirely (winter mode).
• In-between: Feed sparingly, only wheat-germ/spring formula, only what's eaten in 2 min.

Why This Works

Koi metabolism tracks water temperature, not air temperature. Active fish digest food; inactive fish don't. Uneaten food rots → ammonia spike → crash. A pond thermometer confirms, but behavior is the ultimate indicator.

Practical Tip

Keep a floating thermometer. If water >60°F and fish active, feed. If <55°F, stop. Between 55–60°F, use judgment. Never feed if a cold front is forecast within 24 hrs.
