How to Feed Frozen Bloodworms to Fish

Frozen bloodworms (non-biting midge fly larvae from the family Chironomidae) are a great way to add some protein to your fish’s diet.

Even picky eaters tend to gobble these little guys up.

But, if you’re new to the hobby, you may be confused about how you’re supposed to feed these to your fish.

Have no fear! It’s really easy and I’ll be glad to go over how to do it.

Feeding Frozen Bloodworms to Fish Step-by-Step

Feeding bloodworms is quite simple.


  • Frozen bloodworms
  • Small cup
  • Turkey baster (optional) 
  • Timer (optional but very handy)


  1. Put several ounces of tank water into the cup and add a cube of frozen bloodworms.
  2. Wait several minutes for the bloodworms to thaw. You can speed this up by stirring a few times. I recommend setting a timer so you don’t forget your defrosting worms.
  3. Once the bloodworms are thawed, you can just dump them into the tank, or if you want a more controlled method, suck up the worms into a turkey baster and squirt them into the water.

Yep, it’s really just that simple.

You thaw them out and they’re ready to be fed to your fish.

Final Thoughts

There really isn’t much to feeding frozen bloodworms. Just thaw and add to the tank.

You might see some products on the market that are supposed to be bloodworm feeders, but I’ve not found one that works well.

Either the holes are too small, and the worms don’t come through, or the holes are too large and everything just falls through all at once.

I’ve never found one that made things easier than the steps I’ve outlined above.

I hope you find this article helpful.

I wish you and your fish the very best!
