Birch Cones are great addition to any shrimp tank. They provide a media for biofilm to grow and release tannin overtime which contains beneficial properties. They also provide small hiding spaces for shrimplets to seek refuge.
We sell these cones in 1 oz bags, each bag should contain 25-30 cones.
We recommend boiling all botanicals before use in your aquarium. This is good practice when adding anything new to your aquarium
