How To Breed Bloodworms?

Simply buying live or any other type of bloodworm is not enough to have a good population in your tank; you must create suitable conditions for these worms to be able to survive.

You also have to be extra careful while handling them as they tend to deliver painful bites that can cause allergies.

As these bloodworms grow to become adult midge flies, there is a chance that they will fly away from the area.

You need to have an enclosed space that restricts these bugs from flying away. This will force them to lay eggs in the area that you created.

To keep these worms alive, you must have a tank with sterile water. You also must have an active pump.

Since they also feed on decaying matter, you simply need to keep adding manure from farm animals to the aquarium, as it serves as food for the worms.

How To Cultivate Bloodworms?

Breeding bloodworms can be difficult. If you don’t want to go through the hassle of creating a habitat for these worms, you can use the following step-by-step method to keep them alive for fish food and bait:

Instead of hunting live bait bloodworms, simply purchase them from an aquarium store. However, if you are living in a coastal area, you can easily find these worms in marine waters.

You must remember to wear gloves while catching them as there is a high chance of them biting you.

Once you catch some bloodworm, make a tiny incision near the collar muscle using a knife. You can find the collar muscle below the worm’s head.

Now hold the bloodworm by the tail, and squeeze its guts out from the small incision near its head.

While taking out the guts, you will notice two nerves popping out with the guts. Do not damage these nerves in any manner. Dispose of the guts apart from the two nerves that popped out.

After clearing the guts, carefully place the bloodworm on a clean piece of paper and put it inside the fridge.
