In this article, we’ll take a closer look at the popular YoYo loach and explore its potential role as an algae eater. Keep reading to discover the truth about these fascinating fish, and learn about other helpful aquarium inhabitants too.

Though they aren’t primarily known for consuming algae, YoYo loaches can contribute to a tidier tank. Want to find out just how they can aid your aquarium’s ecosystem? You’ve come to the right place!

Are YoYo Loaches Algae Eaters?

Let’s cut to the chase: YoYo loaches do eat algae, but they’re not the most efficient algae eaters out there. While they can help to control algae growth, it’s essential to remember that they can’t handle excessive algae problems on their own.

Algae – The Good, the Bad, and the Ugly

Having a small amount of algae in a freshwater aquarium is normal and can even be beneficial. Typically, algae provide oxygen, food, and shelter for certain fish and invertebrates. However, algae can also quickly get out of hand and cause issues, such as blocking sunlight and deoxygenating the water.

What Do YoYo Loaches Eat?

YoYo loaches are scavengers by nature and have a varied diet. In addition to munching on algae, these omnivorous fish enjoy sinking pellets and wafers, frozen foods, live foods, and blanched vegetables. While they will consume some algae, don’t rely on them as your primary algae control solution.

Alternative Algae Eaters

If you’re looking for more efficient algae control, there are several other species that can help. Consider some of the following options:


Plecostomus or plecos are among the most well-known algae eaters in the aquarium hobby. These catfish come in various sizes and consume large amounts of algae. Bear in mind, however, that larger pleco species may require bigger tanks.


Otocinclus catfish are small, peaceful fish that devour algae with enthusiasm. They typically do well in community tanks and often work well together in groups to tackle algae problems. However, they can be sensitive to water quality, so be prepared to give them the proper care.


Amano shrimp, cherry shrimp, and ghost shrimp are some of the freshwater shrimp species that can help control algae. They are typically best suited for small tanks and nano aquariums.


Many freshwater snails, such as Nerite snails and apple snails, also feed on algae. By keeping a few snails in your tank, you can reduce algae growth. Just be careful as some snail species can reproduce rapidly and become a problem in their own right.

Efficient Algae Control Methods

While fish, shrimp, and snails can help reduce algae in an aquarium, it’s essential to address the root causes of algae growth. Here are some effective algae control strategies:

  • Limit light exposure (excessive sunlight can lead to algae blooms)
  • Monitor water quality – check and maintain appropriate nitrate levels
  • Perform regular water changes
  • Avoid overfeeding your fish
  • Use appropriate filtration and water movement
