Freshwater Invertebrates provide an interesting and colorful addition to most any freshwater community aquarium. In the past there were few freshwater invertebrates available within the aquarium hobby, which limited the diversity of the freshwater community aquarium. However, the aquarium hobby now has many species of freshwater invertebrates that add both diversity and functional benefits to the freshwater community aquarium. From snails, shrimp, lobsters, crabs, clams and other freshwater invertebrates can help keep an aquarium healthy, clean and they also provide viewing pleasure themselves.
