Why do fish need algae?

Answer 1

Plants are great hiding places for fish who are being bullied by other fish or newborn fry. If you have live plants, they can provide the necessary oxygen for your fish to survive. The plants can filter out waste, as well as provide an extra food source for your fish. Plants also assist in algae prevention.... there ya go! I hope this was helpful.

Answer 2

Water Plants do the same thing in water as terrestrial plants do on land. They use up Carbon dioxide and produce Oxygen during the photosynthesis process. They also use up nitrates that are the product of aerobic bacteria doing its job converting the Ammonia and Nitrite (products of fish living and pooing etc) in a cycled filter. The use of 'fine' air bubbles can increase the fish holding capacity of an aquarium by increasing the amount of oxygen (Air) uptake in the water.

Answer 3

Algae is one of natures water cleaners. The presence of algae indicates that nature is doing its job and is supplying plant life to help keep your water healthy by removing (using up) some of the excessive Nitrates that always develop in any aquarium that is occupied by fish or snails etc. If you have an excess of algae, it means your tank needs more plant life to cope with all the waste products that are in your water.

Answer 4

Plants can benefit from fish by expelled co2, which plants use to make the fuel used for growth. Fish leavings can also act as a fertilizer for plants. Many fish groom plants and help eat competing micro organisms such as algae and bacteria that may overwhelm plants. In some cases certain fish may turn over the substrate to provide a healthier environment for plants.
