Does Excessive Algae Growth Affect Guppies?

The problem for many when it comes to algae is that it is hardly a nice sight to have your aquarium coated in an unattractive green color. In addition to this, algae will likely consume the majority of your tank's nutrients and oxygen, especially during outbreaks. Too much algae will most likely starve the rest of your tank from their required nutrients, which can be harmful and deadly for your guppies!
How Do Guppies Contribute to Algae Growth?
Guppies most definitely do contribute to the growth of algae, as well as help reduce the numbers. It sounds a bit contradictory, but hear us out. Algae growth is certainly sped up by their food consumption, and algae typically diet on waste produced by guppies and other fish.
Guppies do tend to help with algae growth more than other fish due to their excessive eating and their overproduction of body waste. The food waste residing in your tank will be the primary food source for algae, providing them with the required nutrients. Overfeeding your fish will certainly lead to excessive algae growth as well as a poor filtration system. So, make sure you keep on top of things!
Guppies enjoy eating almost everything put in front of them, which is why it is so crucial that you do not allow them to just feed on algae or bloodworms. You should provide them with a balanced and nutritional diet, helping them grow healthy and happy. They will make for brilliant algae eaters, but do not expect them to fix any algae breakouts you are experiencing - they are only little!
