Many people feed bloodworms to their betta fish as a healthy treat, but in reality, these small creatures can provide your fish with an excellent source of protein.
However, it’s essential to only feed them once or twice a week. Otherwise, they could develop obesity and other health issues; additionally, rotting in the tank can lead to ammonia spikes which could prove fatal for your betta and other fish in the aquarium.

Feeding Guidelines
When feeding your betta fish bloodworms, be sure to pay close attention to the amount and instructions printed on the can. Generally, these instructions state to give them no more than what can be consumed within two minutes of consumption.
However, this may not be the most accurate way to measure how much food your betta consumes. As they tend to discard any uneaten food, it can be difficult to determine how many bloodworms they’re actually eating.
Therefore, it’s essential to monitor how much food your betta consumes and remove any leftover food from their tank as quickly as possible.
Overfeeding bloodworms to your betta can cause digestive issues and other health problems such as swim bladder disease. This condition often follows constipation and occurs when the fish’s swim bladder becomes enlarged. Ammonia spikes in the water may also contribute to this issue; thus, testing water parameters at least once a week with a fish tank test kit is recommended for optimal fish health.
Freeze-Dried Bloodworms
One of the simplest ways to feed bloodworms to your betta fish is with freeze-dried worms. You can purchase these type of worms in small tubs and store them up to six months in your freezer before feeding them to your fish.
Freeze-dried worms offer a cost-effective and convenient alternative to live or frozen bloodworms, however they lack essential nutrients like protein. A high quality pellet or flake of bloodworm larva will provide more nutrition than freeze-drying alone can provide.
Before feeding your betta freeze-dried bloodworms, be sure to soak them in tank water for 15 minutes first. This will help the worms soften and not bloat up in your fish’s stomach, potentially resulting in a blockage.
When feeding your betta with freeze-dried worms, it is important to not overfeed them at once. Doing so could disrupt the balance of nutrients in the tank and lead to ammonia spikes.
Live Bloodworms
Bettas enjoy eating bloodworms, but too many can lead to health issues for your fish. This includes constipation which could eventually lead to other issues like swim bladder disease.
When feeding bloodworms, the first rule to remember is that they should always be cut up into small pieces. Your betta can only digest pieces the size of a pea, so feed them one at a time to minimize waste and ensure optimal digestion.
Freeze-dried bloodworms are an ideal substitute for live ones, as they can be stored in your fridge for extended periods. Unfortunately, they have less nutritional value and a greater potential risk of contaminating water sources.
If you opt to feed freeze-dried bloodworms, it is essential that they be dethawed before adding them to the aquarium in order to prevent rotting and impacting water quality. Doing this also helps prevent bacterial infections which could lead to diseases in your fish.
Frozen Bloodworms
Frozen bloodworms are an easy-to-feed option for betta fish. They come in individual cubes or slabs that hobbyists can break apart into smaller pieces.
These are ideal for bettas that cannot eat live food and those who do not feel confident handling or freezing live bloodworms. Furthermore, since they come in smaller amounts than freeze-dried worms, many tank owners find them an economical choice.
However, it is essential to remember that too much betta food can be detrimental for your fish. Excess can cause constipation, swim bladder disease and ammonia spikes.
No matter which bloodworms you feed your betta, always adhere to the manufacturer’s feeding instructions in order to avoid overfeeding and wasting money. Aim for one or two meals a week with small cubes of bloodworm food into the aquarium – this will help avoid ammonia spikes and other problems associated with overfeeding.
