How to: Making Artificial Egg Laying Strips

by Jennifer Macke

Most newts lay their eggs on aquatic plants. There are several reasons why you might want to provide plastic strips for egg laying.

  • Clear strips make it much easier to find the eggs and to follow their development.
  • You can cut them off without destroying aquarium plants.
  • Some newt species actually prefer plastic strips to live plants. In my experience, Triturus karelinii will consistently use strips in preference to plants. Notophthalmus and Cynops species that I have tried did not use the plastic strips if plants were available.
  • If you want to ship your eggs to someone else, plastic strips make the job easier. The strips will not decay during transport.

  • Clear plastic trash bags (any size)
  • Something heavy (in this case, clay "pot feet")
  • Something to attach the strips (in this case, lead ties from aquarium plants)
