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.

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.

Upon the arrival of your Glassworms thoroughly rinse them with chemical-free pre-chilled water at approximately +5°…10°C until their runoff water is clear and clean. When placing them in your live Glassworms keeper or other containers make sure that your worms are no thicker than 1 cm. Keep a low 2 – 3 cm level of cool freshwater above them without covering their container since they need to be able to breathe. Keep your Glassworms in a fridge at +3°…4°C. To keep your worms fresh they should be rinsed at least once a day. Use only chemical-free pre-chilled water at the same temperature you keep them in when rinsing. Do not use aquarium or room temperature water. 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.
