Freshwater fishes are a diverse group of aquatic animals that live in freshwater habitats, such as rivers, lakes, and ponds. Two common types of freshwater fish are daces and ides. Daces are small, slender fish that are usually found in fast-moving streams and rivers. They have a long, slender body with a pointed snout and two dorsal fins. Ides are larger fish that inhabit slow-moving rivers and lakes. They have a deep, compressed body with a large head and a single dorsal fin. Both daces and ides are important food sources for many species of birds and mammals.
