Do you have a build up of algae in your tank and you are worried if your guppies will eat it. Do guppies eat algae?
Guppies will eat the algae in your aquarium, Algae is a a good food source because it is high protein and is a nutritious meal, Even guppy fry can eat algae. The algae will do no harm to the guppies.
Are Algae Good For Guppies?
Yes, algae are suitable for guppies consumption, but they are weeded most of the time because they extract nutrients/oxygen primarily meant for guppies from getting to them.
Algae that serve as food will eventually be hindered to the growth of the guppies and live plants; the led light around the aquarium, especially in the day, will find it difficult to penetrate into the tanks, especially if algae are on the surface of the water.
Please note, you don’t have to plant algae before they appear. They grow on their own, provided there are nutrients in your water. Guppies feed on them to get nutrients, but algae sap nutrients that should be exclusive to guppies.
Types of Aquarium Algae
The same way we have different species of guppy is the same way there are varieties of algae, and algae should be green in color.
Those that have different colors shows there are issues with the water quality. The deposition of residual nitrate or dissolved phosphate gives red or brown algae. Types of algae you will find in your aquarium are
Green carpet Algae: This type of algae is the most common; they can occupy the aquarium within a short period if they are not controlled. They don’t only grow on water, you find them on your decorations, rocks, walls of the tank.
Green water: These algae though nutritious for guppy but deadly because they change the color of the water to the murky green. This condition will reduce the amount of oxygen in the aquarium and prevent lights from getting to the fish.
Brown Algae: This is prominent in a new aquarium with little or no light penetration. The presence of this algae will create a brown film sheet at the bottom or sides of the aquarium water though you can wipe this brownish film by gently scrubbing the affected part of the aquarium.
Red or Beard Algae: Unlike brown algae that form brown film sheet, red algae form a layered green carpet grass which can be up to 3cm in height. Guppies have plenty of this algae to eat whenever they are formed, but it saps rich nutrients in the aquarium, and it is difficult to remove if it is allowed to proliferate.
Guppies can be classified as omnivorous, and they eat virtually all fish feed. Wild guppies feed on algae because it is the available food mot times though aquarium guppies also eat algae that grow in their habitat.
Other guppies foods are daphnia, bloodworms, mosquito larvae, shrimp while their fry prefers algae in the nursery stage, baby brine shrimp, crumbled flakes, and the likes. Algae is a perfect food of guppies because it has all the nutrients, but it grows faster than what guppies can consume, and it eventually does more harm than good.
