Banana Worms (Micro Worms): Culture, Feeding & Care Guide

Supercharge Fry Growth with Banana Worms

Banana worms, also known as micro worms (Panagrellus nepenthicola), are a top-tier live food choice for aquarium hobbyists looking to boost fry survival and accelerate growth. Their small size (~50 microns wide and 1–2 mm long) makes them ideal for newly hatched fish and nano species.

How to Culture Banana Worms

1. Prepare the Medium: Use instant oatmeal, baby cereal, or mashed potato flakes mixed with water to a porridge consistency.

2. Inoculate: Spread your starter culture over the surface of the medium.

3. Maintain: Cover with a breathable lid (or ventilated container) and keep at room temp (20–27°C).

4. Harvest: In 3–5 days, worms will climb the container walls—just scrape them off with a clean finger or cotton swab.

Pro Tip: Refresh medium every 2–3 weeks to prevent mold and extend culture life.

Feeding Your Fish
