Bloodworms are a favorite food of most fish, but it’s important to know how and how much of them to feed. Below we answer what fish eat bloodworms and how you should feed them to the fish.

If you are an aquarist, and you have a range of beautiful fishes in your tank like mollies, betta, cory catfish, clownfish, angelfish, goldfish, etc., you must be aware of bloodworms and how beneficial they are for your little water babies.

But do you know that despite the range of great advantages, there can be serious problems if you don’t know what quantity of bloodworms should be fed to different fish?

What Are Bloodworms

In this article, we will talk about the freshwater and saltwater fish species which can consume bloodworms and how often you should feed them with these worms to keep them healthy.

Time to put on your reading glasses!

Types of Bloodworms

Bloodworms can be purchased in three forms. Here are a few details on each of the types:

Live Bloodworms

Live bloodworms are fresh and packed with nutrients. This is great for fish, especially during the breeding season when they require a nutrient-rich balanced diet.

Despite the advantages, you can only store live bloodworms for a short time; they must be fed to the fish within 2-3 days of purchase. Otherwise, they might pupate and evolve into adult midge flies.

This is a problem since you have to purchase them frequently.

Feeding dead worms to your fish are the last thing you want to do, especially when you want to keep diseases at bay.

You should know that live bloodworms are a little difficult to find at pet shops since they usually only keep frozen or freeze-dried ones.

Frozen Bloodworms

Frozen bloodworms are a better alternative, as these worms can be easily stored for up to 6 months.

They are easy to find and have a lower chance of transmitting diseases to the fish.

This happens due to the fact that most of the disease-causing bacteria die when they are frozen into cubes and sheets.

The frozen bloodworm can be a little less in nutrients compared to live bloodworms.

When you are feeding these to the fish, refrain from dropping a whole cube directly into the fish tank.

This will cause a sudden drop in the temperature, increasing the risk of temperature shock. Thaw them a little before dropping them into the tank.

Freeze-Dried Bloodworms

Freeze-dried bloodworms are the cheapest of the three.

If you are on a tight budget, these are the best option for you. However, freeze-dried bloodworms have the lowest nutritional value compared to the other two.

Apart from being cheap, they don’t need any additional preparation time. Just soak them a little in water before feeding them to fish, and you are set to go.
