One of the most common questions pond owners ask is whether or not fish need light to survive. While pond fish do require some light, the amount they need is not as great as people may think.

Fish also need light to digest food. The protein in algae, aquatic plants, and small invertebrates is broken down into small molecules in the fish’s stomachs only if the fish can see them.

Therefore, if your pond doesn’t have any light, the fish will not be able to eat and will eventually die.
