Ocean Nutrition Frozen Bloodworm
Single-ingredient frozen bloodworm, a natural high-protein treat. Ocean Nutrition Frozen Bloodworm is whole red mosquito larvae, flash-frozen and supplied in a 100 g blister of ready-to-thaw portions. It's a long-standing favourite for tropical freshwater fish, offering a higher-protein change of pace from a daily flake or pellet diet.
Key features
- Single ingredient — whole bloodworm, nothing else in the pack.
- Whole-animal form — flash-frozen to keep the larvae intact, around 1.5 cm each.
- Blister portions — each cavity is a ready-to-thaw feed.
- High protein relative to a dry staple — useful as an occasional boost rather than an everyday base diet.
- Readily accepted — one of the most reliably eaten frozen foods for finicky freshwater fish.

Suitable for, and not suitable for
- Suitable for a wide variety of tropical freshwater fish, from small community species up to larger omnivores and carnivores that can take a 1.5 cm larva.
- Not a complete standalone diet — rotate it with a staple flake or pellet rather than feeding it exclusively; bloodworm alone is not a balanced long-term diet.
- Not marketed by the manufacturer as a marine food — this pack is formulated and sold for freshwater tanks.
How to thaw and feed
Snap a portion free from the blister and thaw it in a little tank water, then add the thawed larvae to the tank. Never refreeze a thawed portion — feed it or discard it. Keep the remaining blister frozen between feeds, and if the pack arrives partly thawed on a warm day, transfer it to your own freezer straight away and use it promptly rather than refreezing it.
Which Ocean Nutrition frozen food should I feed?
| Food | Animal size | Best suited to |
|---|---|---|
| Bloodworm (this product) | Whole, ~1.5 cm | Tropical freshwater fish |
| Artemia | Whole, ~1 cm | Small community fish, nano fish, freshwater and marine |
| Chopped Mussel | Chopped | Marine fish and invertebrates |
| Chopped Cockle | Chopped | Larger predatory marine and freshwater fish |
Bloodworm is the freshwater staple treat of this range; reach for the marine-suited packs for a saltwater tank instead.
Warranty and delivery
As a frozen product this pack ships and must be stored frozen. There is no manufacturer warranty on a consumable food item; the consumer guarantee under Australian Consumer Law — that the product is of acceptable quality and matches its description — applies as it would to any packaged food. Transfer the pack to your own freezer as soon as it arrives.
Common questions
Is bloodworm a complete diet on its own?
No. It's a high-value treat and protein boost, best rotated with a staple flake or pellet rather than fed as the only food.
Can I feed this to marine fish?
The manufacturer markets this product for tropical freshwater fish; it isn't formulated or sold as a marine food.
Will bloodworm cause allergic reactions in people who handle it?
Bloodworm (Chironomid larvae) is a recognised allergen for some people who handle it regularly — wash your hands after feeding and avoid it if you know you're sensitive.
How much should I feed?
Offer only what the fish will finish within about 5 minutes, 2 to 5 times a day, and remove uneaten food so it does not foul the water.
Can I refreeze a thawed portion?
No. Once a portion has thawed, feed it or discard it; refreezing lowers food safety and quality.
