Perform regular tank maintenance

Performing regular tank maintenance is the primary way to prevent your guppy fish aquarium from algae.

Regular tank maintenance and water change will keep your guppy’s aquarium water clean and free from any harmful toxins.

Algae develop in dirty water.

We usually avoid regular maintenance, which results in algae development in our aquarium. 

Avoid adding artificial light.

Enough light is also a source of algae development in your guppies aquarium.

Keeping a low-light environment will help you prevent algae on your guppies aquarium.

You don’t need artificial light if you have an aquarium where natural light comes.

Also, guppies don’t require artificial light. If the place where you have your guppies aquarium is darker than usual, then you can go for artificial light. Otherwise, there is no need.

Artificial light becomes the reason for algae development as most of them process their nutrients by photosynthesis.

Prevent your guppies aquarium from direct sunlight

So much direct sunlight will also promote algae growth in your guppies aquarium.

Consider keeping your guppies aquarium in a place where there is no access to direct sunlight if your guppies aquarium contains algae. 

Conclusion:

Guppy fish do eat algae.

But, you must know that guppies will not feed on a large portion of algae.

Guppies will feed on algae to extract small plant nutrition requirements for them.

This means that feeding on algae will be a tiny portion of their daily diet requirement.

Guppy cannot rely on algae as their food. Guppies are omnivore fish and require both plant and meat matter food in their diet.

Provide your guppy with high-quality pellets, flake food, bloodworms, tubifex worms, and brine shrimp to ensure faster growth and enhanced color.

Homemade food like blanched vegetables will also do great for your guppies.
