Microworms are a live fish food that many aquarists, including my self use to feed their fish.

They are especially goof for fry (fish babies) as they help to fatten them up, they are also great for adult fish and pregnant female fish.

They are very easy to culture.

In order to start off a microworm culture, you will need to buy some microworms, you can buy these worms in my eBay shop which specialises in aquatics.

Equipment you will need:


Square plastic container (ice cream tub will be ok)

Small paint brush, Water spray bottle, Porridge oats (any brand, Yeast, Water, Mixing bowl.

First: With a mixing bowl, add a few hand fulls of oats and a pinch of yeast. Give a quick stir and add water until the porridge goes runny. Leave to stand for five minutes and you will notice that the water gets sucked up. Add some more water until runny again.

Secondly: Tip the runny mixture into the ice cream tub. The tub should be less than a quarter full. Leave to sit for 5 minutes.

Thirdly: add the packet of microworms to the top of the mixture and give it all a good stir.

Fourthly: Lightly spray the ice cream tub with the water and then leave the culture alone for a day or two.

After 1-3 days, you may notice that micro wriggly worms. If you hold the tub upto the light you will see thousands of tiny little microworms wriggling around the corner.

When it gets to this point, simply take your paint brush and gently brush it along the top, leaving the oats begind. Then dip it into your aquarium and you will see the worms wriggle off and the fish will be going mad for them. All of my fish, adults and babies love them.

If the culture starts to go dry just simply spray it.

After around 2 weeks, you may want to start a new culture as it does start to smell slightly. all you have to do is taka around 2 tablespoons full of the old mixture out and set aside. Then throw the rest of the old culture out. To start again just repeat steps 1,2,3 and 4!
