What are bloodworms?
Firstly it’s important to know that the name bloodworm covers a range of organisms. Here are the two that you are most likely to feed to a goldfish
- Glycera is a family of marine bristle worms that are commonly harvested from shallow marine waters for use as fishing bait and a nutritious delicacy for aquarium fish. They vary in size and are named because their translucent skin allows the red hemoglobin-rich bodily fluids within the worm to show through. They vary in size between a few millimeters to over 30 centimeters. These worms are themselves carnivorous and if not preyed upon by marine creatures, will eat their prey using venom delivered by a projection with multiple sets of jaws!
- Midge Fly red larvae are commonly fed to aquarium fish as Bloodworms. They earn the name due to their vivid red hue which comes from oxygen-carrying proteins in their bodily tissues. Blood midges are a nutritious treat for all kinds of fish and are popular with anglers as bait.
The benefits of feeding bloodworms to your goldfish
Bloodworms deliver some great nutritional benefits to your goldfish, who will also be advantaged by being able to eat a food that is more natural and palatable and provides opportunities to exhibit hunting behaviors and forage for scraps too.
They are very nutritious and are high in protein and iron, due to their haem-rich flesh. If you have a community tank, feed away, as all your fish should enjoy bloodworms. Though they are good for your goldfish, Bloodworms cannot provide all the nutrients your goldfish need and should only be used to supplement a balanced diet.
Bloodworms can be provided in a variety of ways
These worms come in a range of preparations. You can choose:
- Live bloodworms which are supplied alive, wriggling and writhing.
- Frozen bloodworms that come in small frozen blocks. These are easy to store and can be defrosted for feeding to your goldfish.
- Dried Bloodworms also are convenient and can be reconstituted in aquarium water prior to feeding.
How to feed your goldfish bloodworms
Depending on the preparation of bloodworms you have obtained, you will need to either rinse, defrost, or soak your worms in aquarium water prior to use. Glycera bloodworms may need to be chopped up if they are large. The worms can be added via the net, with pipette or tongs. You can even hand feed them too.
Take care not to overfeed your goldfish and limit worms to a couple of feeds per week. Excessive live food can increase the risk of transmitting parasites and diseases so observe your fish carefully after introducing this new food.

I have been working in the tropical fish industry for over 30 years now and I’m still learning. Everyday is a school day in this hobby. In my spare time I play golf very badly!
