Banana Worm Starter Culture For Sale

Banana worms, Panagrellus nepenthicola, are prolific small nematodes that are great for feeding fish fry. Banana worms (Panagrellus nepenthicola) are not the same organism as parasitic banana nematodes (Helicotylenchus dihystera) that are known to infest banana tree roots. Banana worms are slightly smaller than walter worms and microworms. They measure at 40 microns in diameter and 1.5 mm in length. Despite their small size, they are one of the most prolific nematodes. While banana worms sink in water, their lighter weight allows them drift in the water for a longer time before reaching the base. Microworm and Walter Worm are closely related species to Microworms in the phylum Nematoda. For free swimming nematodes, consider Vinegar eels.

Banana worms cultures are very simple to start and maintain. Banana worms will survive in a wide range of temperatures but will result in the highest yield at 20 to 27 degrees Celsius. Only a container, oatmeal, and yeast is required to culture banana worms. First, add a 3 cm layer of moist oatmeal on the container. Next sprinkle a pinch of yeast on the surface and add a starter culture. It is important to maintain a moist surface on the culture at all times. The culture will be ready to harvest within a few days or until the worms start to crawl up the sides of the container. The worms can be harvested by either swiping the worms off the sides of the container or by skimming off the top layer of the culture with a dense population of worms. The latter method may result in grabbing the culture media along with the worms. In this case, the worms can be cleaned in a separate container with water and fed to the fish with a pipette. More of the smaller juvenile banana worms will be collected in the latter method as well compared to the first method.
