How to Keep Bloodworms Alive

Updated February 21, 2017

Live protein is an important source of nutrition for pet reptiles, amphibians and fish. Though proper live bloodworms are rare in the U.S., pet stores sometimes refer to aquatic blackworms as bloodworms. Blackworms are low-maintenance critters you can purchase in bulk from pet stores and aquarium supply companies. For best results, purchase the worms on the same day they arrive at the store.

Fill several large bottles with tap water and let them sit for 48 hours to age. Water straight from the tap may contain chlorine, which can harm the worms. You must always age water for 48 hours before using it to store or rinse worms. Store the aged water in the refrigerator.

Transport worms in a cooler on the way home from the pet store. If ordering worms online, avoid ordering in hot weather since worms can die and decay in transit.

Place worms in an open plastic container and add just enough aged water to cover them. Store the container in the refrigerator.

Rinse the worms with cold, aged water daily.

Remove and dispose of any dead worms in the container. If many worms start to die or if the container smells foul, throw away all of the worms to prevent contaminating other worm containers or pets.
