Harvesting microworms can be one of the less fun aspects of culturing live fish foods. When first culturing various live worms for fish food, many people consider the actual harvesting to be one of the less pleasant aspects. I certainly do not blame anyone for feeling this way. Harvesting your microworms is not difficult at all, and I will share some of the easiest methods I have found.
Perhaps the most obvious methods is to simply use a Q-TIP and wipe off any microworms that are climbing up the sides of the container. I find there are usually enough worms crawling there that I can provide my baby bettas a nice meal or snack. Other options include using a toothpick in the same manner. These two methods are quick and efficient, two factors I appreciate when dealing with these live fish foods.
If you eventually become comfortable with the above methods of harvesting your worms, then you can move on to a technique that might make many people queasy. You can simply use your fingers to swipe off any microworms from the walls of the culture container. Since microworms are not harmful to humans, there is no reason this method should be avoided. I would always recommend a thorough hand washing after touching anything near your culture.
Once you have the microworms on your finger, Q-TIP, or toothpick you can directly swish them into the fish tank, trying to spread the worms evenly throughout the tank to give all your baby fish a chance at finding them. The worms will sink to the bottom, but can remain alive for days at a time, providing your fry with plenty of food if you don’t get a chance to clean the tank of leftovers soon after feeding.
Some people have microworms that do not always climb the sides of the container. Various methods have been described for harvesting in this scenario. Probably one of the best is to lay a damp paper towel on top of the surface of the worms. Within several hours, you will be able to scrape a spare plastic spoon across the surface of the paper towel and harvest pure microworms. If you are satisfied that you will be able to culture and harvest your microworms efficiently and easily, why not head on over and purchase a microworm starter culture today.
