Grindal Worm Care Guide Grindal worms (Enchytraeus buchholzi) are hardy, easy to culture, and reproduce quickly under the right conditions. Follow these simple care tips to keep your colony thriving: Temperature: 68–77°F (20–25°C) is ideal. Avoid temps above 80°F, as colonies may crash. Container: Use a small plastic box or tub with a tight-fitting lid. Drill or poke small air holes. Medium: Moistened coconut fiber, potting soil (without fertilizer), or sponge pads all work well. Keep damp, not waterlogged. Feeding: Provide small amounts of food every 1–3 days. Oatmeal, soaked dry cat food, bread, or powdered fish food works well. Remove leftovers to prevent mold. Moisture: Keep the culture moist but never soggy. If too dry, worms burrow deep; if too wet, they may die off. Harvesting: Scrape worms from the surface or place food on a piece of plastic/mesh—worms will climb on it for easy collection. Lighting: Keep in a dark or shaded place; avoid direct sunlight. Maintenance: Refresh substrate every 1–2 months to prevent souring. Start backup cultures for reliability. With regular care, your culture will produce a continuous supply of protein-rich live worms for your fish, frogs, and reptiles.
