🐟 Feeding Microworms to Fry

To feed:

• Use a cotton swab, finger, or small spatula to scrape microworms off the container walls.
• Dip the swab into the fry tank.
• Fry will chase them enthusiastically!

🌀 Feed 1–2 times daily depending on fry density. Always remove uneaten worms if water becomes cloudy.

🔁 Culture Maintenance Tips

• Add a small bit of oats + water every 1–2 weeks to refresh the medium.
• If the culture begins to smell sour or turns dark brown, it’s time to restart.
• Always keep a backup culture going!

💡 Pro Tip: Rotate microworms with vinegar eels or baby brine shrimp to give your fry the best variety in their diet.
