What is a Bloodworm?
The bloodworm, or chironomid larva, is a small red worm measuring between 1 and 2 cm. It lives in the muddy sediments of stagnant or slow-moving freshwater. Its bright red colour comes from the haemoglobin it contains, allowing it to survive in low-oxygen environments. Widely used as live bait for angling, it is also a choice food for aquarium fish, especially discus, cichlids, and tropical fish.
The Different Types of Bloodworms
Live Bloodworms
Live bloodworms are the most effective for fishing and aquariums. They can be stored for a few days in the refrigerator in a ventilated container with a little water. They are sold under names like "Bloodworms - Live Bait" or "Live Food - Red Bloodworms 90ml". Ideal for fussy fish, they stimulate their hunting instinct.
Frozen Bloodworms
Frozen bloodworms are a practical alternative, sold in blocks or portions (e.g. "Pure Bloodworms 30g portion"). They retain good nutritional value and can be stored in the freezer for several months. Thaw quickly before feeding.
Freeze-Dried Bloodworms
Less common, freeze-dried bloodworms are very light and rehydrate in water. Convenient for transport, they are mainly used in aquariums for small fish.
Blister Pack Bloodworms
"Red Bloodworms Blister Pack 500g" is a packaging aimed at regular anglers. These are live worms presented in compartmentalised trays, ready to use.
How to Choose Your Bloodworms
Quality Criteria
- Freshness: live worms should be active, bright red, with no unpleasant odour.
- Cleanliness: opt for pure bloodworms, free from debris or mud.
- Packaging: for fishing, choose blister packs or bags with good oxygenation.
- Origin: some products are farmed, guaranteeing better hygiene.
Bloodworms for Fishing
For fishing, live bloodworms are essential. They attract white fish (roach, bream) and predators. They are available at fishing shops or Decathlon (reference "Live Bloodworms Decathlon"). A 500g blister pack costs between €8 and €15.
Bloodworms for Aquariums
In an aquarium, live or frozen bloodworms are suitable. They are rich in protein and fatty acids. Caution: live worms can introduce bacteria if poorly farmed. Frozen versions are safer.

Where to Find Bloodworms in the Wild
You can catch bloodworms in stagnant waters rich in organic matter: ponds, pools, ditches. They hide in the surface mud. To harvest them, use a fine net or sieve, and rinse to remove impurities. Caution: wild harvesting may be regulated. It is often easier to buy them in stores.
Common Mistakes to Avoid with Bloodworms
- Improper storage: do not leave live worms in stagnant water for too long. Change the water regularly and keep them cool (4-8°C).
- Overfeeding: in an aquarium, give small amounts to avoid water pollution.
- Mixing with other baits: bloodworms store better alone.
- Using dead worms: dead worms decompose quickly and can harm fish.
Usage and Maintenance Tips
For Fishing
Place the worms in a ventilated container, kept cool. Use one live bloodworm per hook, threading it gently. For fine fishing, mount a bloodworm as bait. The bloodworm is an irresistible bait for fish.
For Aquariums
Feed live or thawed worms in small amounts, once or twice a week. Remove leftovers after a few minutes. Pure bloodworms 30g portions are convenient for dosing.
