Fish for the classroom

Freshwater Fish

Available in a wide variety of species, freshwater fish can help young students learn about biological diversity, environmental traits and breathing abilities. For instance, unlike other tropical fish, Bettas gulp air from the water's surface to help them breathe. That's why they can live in non-aerated bowls.

While Bettas should be kept alone in their home, schooling fish like Tetras, Barbs and Danios thrive in groups, where they feel secure, and in aerated aquariums. Aquarium themselves can be a useful tool for teaching basic chemistry.
