What Are Bloodworms?

The most common question we get at the start of any conversation with customers is ‘What is a Bloodworm?’. Bloodworms are a type of larvae found in freshwater pools and ponds and are typically farmed around the north east coast of America. Bloodworms are a popular food for freshwater fish worldwide and are commonly used as bait for fishing. Almost every fish species will eat them as they are a great source of protein, and whilst your fish will love it, it’s vital to remember the importance of a varied diet. Bloodworm acts as a laxative (an All-Bran for fish if you like!). Fancy goldfish often suffer from constipation due to too much dried food, and feeding bloodworm regularly helps to keep them…well, regular.

Bloodworm can be purchased in a variety of forms, are reasonably priced and can be bought in handy little packets that need to be kept cool and can only be stored for up to a week. Freeze dried bloodworms are easier to store than frozen, as they do not require the freezer space, it is however significantly less nutritious. Bloodworm can also be purchased as a gel which includes extra added vitamins, is stored at room temperature and has a 2 year life span.

Why Choose Frozen Bloodworm?

Frozen bloodworm is probably the most popular choice of fish food for a number of reasons. It is less expensive than purchasing live food, it is more nutritious than freeze dried bloodworm and is easy to store and prepare.

Frozen bloodworm, as the name suggests should be stored in a freezer, and once thawed should be stored in a refrigerator for no longer than 4 – 5 days. It is mainly sold in blister packs, almost like miniature ice cube trays full of bloodworm, typically 100g in weight. They are easy to add to the tank, and even a tank with only a few fish should be able to eat a whole cube. If there are leftovers net them out and perhaps cut a cube in half next time round. Bloodworm is also sold in slabs or bulk packs, often weighing in at 500g or 1kg. These are less easy to use for smaller aquariums, but reveal a saving if you have a big tank or multiple aquariums.

An additional benefit to feeding frozen bloodworm over live, is the reduced risks of harmful bacteria. The freezing treatment kills the majority of any harmful bacteria, however it is worth noting that poisoning in this way is extremely rare. People often worry about frozen fish food thawing out, either during shipping or in the event of a freezer failure. Most reputable foods are gamma irradiated, which means they are completely free of pathogens, and as long as the packaging is intact, can be frozen without any deterioration to the food or ill effects in general.
