A Glassworm is a type of midge larva called Chaoborus. They are approximately 10 mm in size. Glassworms are almost entirely transparent, except for pairs of black kidney-shaped structures in the front and the back of the body. These dots are the air sacs. They use these air sacs to migrate up and down in lakes. Glassworms breathe through the end of their abdomen and have two small eyes at the front of their bodies. Glassworms are very tolerant to bad water conditions, including chlorine.
It’s one of the primary live foods fed to virtually all freshwater aquatic animals such as fish, frogs, shrimp, snails, salamanders, crabs, crayfish, etc. It is very readily taken by all of them. Feeding live Glassworms to your aquatic animals you will find them much healthier maintaining their true colours. It’s a perfect food for conditioning and breeding your aquatic animals. These worms are laboratory-produced, free of parasite creatures.
Fish love the taste of Glassworms – even the pickiest eaters. You might have a hard time seeing them, but your fishes spot them almost instantly. As they twitch and turn in the water, your fishes’ hunting instincts kick in. They want to rip and rend their prey.
Keep Glassworm bags in a fridge at +3°…4°C. You do not have to feed your Glassworms. Uneaten worms will not foul your aquarium, but do feed according to your aquatic animals and aquarium size.
