To ensure guppies grow healthily and develop vibrant colors, feed selection should be matched to their growth stages and nutritional needs. Here are comprehensive recommendations:
1. Live Baits (Ideal for Fry and Color Enhancement)
Brine Shrimp Larvae: With protein content exceeding 60%, they are the optimal first food for fry, promoting rapid growth. Feed immediately after hatching to retain yolk sac nutrients.
Daphnia: Rich in calcium, it boosts bone development and body color. If wild-collected, disinfect thoroughly to prevent parasites.
Tubifex Worms: Highly nutritious and long-lived in tanks, but monitor for parasite risks.
2. Artificial Feeds (Daily Staples)
Flake Feeds: Easy-to-digest, suitable for all life stages. Choose products with ≥45% protein.
Micropellets/Slow-Sinking Granules: Brands like Jipinhong and Sensen include color-enhancing ingredients. 0.5–0.6mm granules are most palatable.
Frozen Feeds: Freeze-dried brine shrimp, for example, preserve live bait nutrition while offering safety and convenience.
3. Fry-Exclusive Diets
Egg Yolk Water: For emergency use only; strictly control portions to avoid water contamination.
Paramecia/Rotifers: Ultra-fine microorganisms perfect for fry within 3 days of hatching.
4. Feeding Guidelines
Frequency: 4–6 small feedings daily for fry; 2–3 for adults.
Variety: Alternate live baits with artificial feeds to prevent dietary monotony.
Water Maintenance: Remove uneaten food promptly and change 1/3 of the water weekly.
Note: Ensure live baits are from safe sources, and opt for high-protein artificial feeds specifically formulated for guppies.
