Single feed bags
Bloodworm - approximately 10mm in length.
Single feed bags each holding approx. 115ml of water with enough bloodworm to feed an average 24-36 inch aquarium.
Recommend to use a soon as possible but will keep for up to a week if kept refrigerated.
This is actually the larvae stage of an insect similar in size and shape to a mosquito, although it doesn't bite or carry disease. Sourced from Poland or Russia, bloodworm are high in iron which is in the haemaglobin type substance that gives them their red colour.
Bloodworm
Blood worm can be stored in the water they are supplied in like brine shrimp and daphnia, or can be drained through a net and stored in newspaper folded over to make a small envelope (they take up much less space in the fridge like this). Either way, it's crucial blood worm is kept refrigerated as it is very susceptible to hot temperatures and will die quickly if it gets too warm.
To feed, drain through a net and add as much as your fish will eat in 5 - 10 minutes. Any not used can be stored in the fridge wrapped in newspaper.
