What do fish eat?
Just as fish are extremely diverse, so are the foods that they eat. While some fish classify as carnivores, others are herbivores or omnivores. Some fish feed on small organisms, algae, or detritus, while others only go after larger prey such as other fish. Typically, the foods that a fish eats vary based upon its biology, size, and environment.

How does water get into a fish’s body?
Water gets into a fish’s body through osmosis, the process in which water diffuses from a higher to a lower concentration. For example, if there is more water outside of a cell than inside, water will try to flow into the cell until there is the same concentration of water on either side of the cell’s membrane.
