Care Instructions:

Scuds (Gammarus): Upon arrival, transfer the tiny shrimp-like scuds into a larger container of dechlorinated or spring water by pouring the contents directly from the shipping jar into the new container. Keep the container at room temperature out of direct sunlight. Gammarus feed on microscopic algae and protozoans normally found in pond water. Introduce aquatic plants to the aquarium if you will be keeping the scuds for more than a week. The plants will provide food as they break down.

Pond Snails: As soon as they arrive, rinse the pond snails with dechlorinated or spring water and transfer them to the aquarium. Snails will feed on algae or decaying plant matter naturally found in the aquarium.

Duckweed: Strain the contents of the shipping container with a small sieve or dip net. Rinse the duckweed in dechlorinated or spring water. Introduce the duckweed to the surface of your aquarium.

Please refer to the living materials literature included with your shipment or check the Materials section of your Teacher Guide for information on dealing with the organisms at the end of the module.
