Where to Buy Live Worms for Aquarium Fish
Bloodworms can refer to a few different types of worm including the two most popular ones; the small red larvae from midge flies (Chironomidae) and the genus Glycera a group of worms that are usually found in marine waters.

Both of these worms are suitable for feeding fish.
Most of the worms that you find for sale are the small red larvae variety, and are not actually worms.
You can buy bloodworms either live, frozen or freeze dried. We're going to take a look at the benefits for each of these, which species of fish will eat them, and how to feed them along with some recommendations of which ones are best for your fish.

All About Bloodworms
Bloodworms, the larvae of the non-biting midge fly, are bright red in color. They have this color due to the red iron-porphyrin protein in their blood and tissue. They can thrive in polluted water with low oxygen levels because of their hemoglobin content.
This creature is one of the primary foods in the aquatic food chain. Almost every species of meat eating fish will consume this worm. It is also used to feed other aquatic animals such as salamanders, turtles, crabs, frogs, shrimp and snails.
Worms from the genus Glycera are a group of bristle worms that are usually found living on the seabed of marine waters. They can grow up to 14 inches and are a creamy pink color. They also have a venomous bite.

You will find that some freeze dried come in Grade A and Grade B. Although Grade A is slightly more expensive, it's worth paying the extra because Grade B are lower quality and can contain non bloodworm particles.
Despite them being the least nutritional, they are the most convenient way to feed your fish.
To feed this food to your fish, soak it for a couple of minutes in water before adding it to the tank. This will soften it.
Freeze dried varieties usually float at the top of the tank, so if you want to feed them to bottom dwellers, soak them for around 10 minutes before adding them to the tank.

Live Bloodworms
Live bloodworms aren't always as easy to find as frozen ones.
They also don't keep as long as the frozen or freeze dried varieties. The larvae life cycle is short, usually just 10-12 days, and they should be used within 2 or 3 days of buying them.

Live worms usually come in a plastic container. You should rinse the worms before feeding them to the fish and don't add any of the water in which they were stored to your tank.
You should store them in the fridge, with enough water to cover the bottom of the container.
They are ideal for large tanks which have many fish.
Whilst live foods are usually more nutritious than frozen foods, they do have a higher risk of carrying infection and disease. For this reason, it's not recommended to collect your own worms or larvae from the wild.

One way to avoid contaminating your tank is to buy your live foods from a reputable breeder.
Live ones are ideal for conditioning fish if you want them to breed; they are commonly used to condition Betta fish.
Feeding them live foods will also bring out the hunting instincts of your fish and you will see more of their natural behaviors.
Frozen Bloodworms
Frozen ones are more convenient than feeding live foods as they keep for much longer (up to 6 months) in the freezer.
They come in a few different forms, from frozen blocks to thin sheets.
One of the benefits of using frozen worms is that it's unlikely they will be carrying any parasites or disease.
To only downside of feeding them frozen worms is you will miss out on watching your fishes' natural hunting behaviors.
When you are ready to feed your fish, fill a small container with some of the tank water and place a cube of bloodworms in, to thaw it out. Once it has thawed, strain the defrosted food to remove the water and excess juices.

Whilst many people add it all to the aquarium, it can be an unnecessary bio-load on the filter as the fish won't eat the juices.
If you only have a small tank, you'll want to cut the cube in half to ensure you don't overfeed the fish. You can judge this by watching them when you add the first few cubes. Time them for a couple of minutes and if there are any leftover worms after this, you've overfed them.
Use the first few times to determine how much you should be feeding your fish. It's better to add less at first and increase the amount you're feeding them over time.
When you add them to the tank, you can either do a mass feeding and add the whole lot over the length of the tank, or you can feed fish directly. To do this you can use either pipette or tongs.
Which Fish Can You Feed Bloodworms To?
All freshwater and saltwater fish that are either carnivorous, or omnivorous.

Bloodworms are known as the ultimate bait fish, because 99% of fish will eat them.
They can provide your fish with lots of protein, but it is important not to over feed them. They should not be used as a complete diet, rather as a supplement to their regular diet which is usually flake or pellet food.
Even though they are rich in iron and protein, they lack other essential amino acids, minerals, and vitamins which your fish need to breed, so always feed them alongside their staple diet.
Bloodworms are also used to condition fish that are about to breed.
They are usually high in protein so are better suited to fish such as Bettas, and any livebearer such as Mollies and Guppies. This is a popular food for Discus, Eels, and Loaches too.
Breeding Your Own Bloodworms
You might think breeding bloodworms would be cheaper and more convenient than buying live ones.
Breeding your own means you known the conditions they have been bred in and you can minimize the risks of parasites and disease. However, breeding them is difficult and not practical for most hobbyists.
Unlike breeding fish, bloodworms can be tricky to breed because you need to have somewhere that they can fully mature into flies – the flies are prone to flying away to lay their eggs elsewhere.
There are four main stages of their life cycle; egg, larva, pupa, and the adult midge. The main difficulty lies in the inability to be able to induce swarming and mating of midges in captivity.
Most hobbyists who breed their own use either tubifex worms or blackworms.
Those looking for a challenge can give it a go, but it won't save you much money, especially if you do not already own everything you need.
Raising bloodworms from eggs is the easy bit. Get some chironomid eggs and keep them in a container with some soil and manure. Add some water and store in a cool, dark place.
Add a little manure each week and the eggs will eventually hatch into bloodworms. You can catch these with a net to feed your fish.
Breeding more bloodworms is the difficult bit. You will need somewhere as big as a greenhouse to allow some bloodworms to develop into adult midges and swarm to produce new eggs.
This makes the process unfeasible to most, it's generally more effort than it's worth.

If you own a pond, you may be able to encourage midges to spawn around it. This would mean that you wouldn't need a greenhouse, you could just collect eggs deposited around your pond.
You may unintentionally encourage mosquito spawning, but this is not necessarily a bad thing as most fish that like bloodworms will also enjoy eating mosquito larvae. Just be aware that mosquitos will bite, whereas midges do not.
