While isopods (pillbugs and sowbugs) can be collected locally in most areas, it may be difficult to locate both types of organisms.

Goldfish, guppies, pond snails, elodea, and mealworms can also be purchased at local pet stores. This may be a better option as it cuts down on transit-stress for the fish.

Goldfish will eat elodea and gammarus. May want to purchase extra.
