Keeping Microworms Alive – Factors That Will Create Booming Microworm Colonies

Some people find it difficult to keep microworms alive. I have had conversation with some people who, for whatever reasons, find it difficult to maintain their microworm cultures. Only once in the past, have I had enough bad luck to have all my cultures go bad at the same time. There are very few road blocks present when you decide to start culturing microworms successfully. This page is dedicated to describing those rare difficulties and how to overcome them. Many of the tips may be scattered throughout the rest of this site, but you will find a good summary of most of them here.

One key factor for keeping your microworms alive is providing oxygen. There are a few options you have to ensuring an adequate supply of air to your live fish foods. I interchange between using a nail to poke several holes in the culture’s lid and just simply not closing the lid fully.

The right temperature is vital to the survival of your microworms. On many sites, I have read that microworms can be forced to multiply faster by propping the container on an aquarium lid, using the heat of the light to crank up the metabolism of this live food. I am not a fan of this option. While it may work in the short term, it is detrimental to the overall amount of time your culture will last for. Your worms may reproduce quickly for a few days or a week, but it will eventually die out much faster. Just provide a more “normal” temperature (neither too hot or too cold) and you will find your microworm culture will stay alive for months.

Your microworms also require an adequate source of food. The easiest way to do this is to mix a pinch of yeast into the culture every time you re-culture the worms. I cannot stress enough how important this is. Above, it was mentioned that I once lost all my cultures at the same time. I believe this is because I neglected the yeast for multiple times of sub-culturing. Eventually this caused all the microworm cultures to crash at once.

This brings me nicely to my last point. You should always have multiple cultures at once. Try to stagger the timing if your re-culturing and you will always have cultures at their prime for harvesting microworms.
