Yoyo Loaches are one of the most popular scavengers in tanks. These tiny fish are active, making it enjoyable to observe them scoot around your aquarium. 

However, you should know their temperament before introducing them to a community tank. Is Yoyo Loach aggressive

It’s time to dive into this post to know the exact answer. Let’s scroll down to discover more!

Is Yoyo Loach Aggressive?

The answer is yes! These aquatic creatures are relatively aggressive with other fish and their species members. 

Although they occasionally get “nippy,” they typically don’t attack the other creatures in your aquarium.

If you keep them in a shared tank, Yoyo Loaches may stick together with more hostile species and bully weaker and smaller creatures. 

Moreover, Yoyo Loaches may bite other species. They are omnivorous, so they can eat both plant and animal-based diets. 

When they devour brine shrimp or bloodworms, their down-the-throat teeth make an apparent “clicking” sound. Thus, they can bite or nip each other, especially during feeding time.

Because of their playful nature, these loaches may easily intimidate or scare other species in a shared tank.

These creatures are opportunistic. They can eat anything they find at the tank bottom, even dead fish. 

If your Loaches show “nippy” signs with other tankmates, you need to quarantine them for a couple of days in another tank to curb their hostile behavior. 

Moreover, if you add these creatures to your freshwater aquarium, placing many plants and caves is best to protect other species. 

Yoyo Loach Tank Mates

These creatures are aggressive, so you must choose the tankmates carefully before keeping them in a community tank. Let’s check out the recommendations below!


Angelfish often reach 6 inches, but sometimes they can grow up to 8 to 10 inches with tall fins and bodies.

They are peaceful and often swim around the middle and lower water column portions. 

These fish may be territorial and get stressed when alone in an aquarium. Thus, it’s best to keep them in a small group. 


Glass Catfish

If you are really into oddball fish, Glass Catfish will be the top choice for your Yoyo Loach tank. 

These strange aquatic creatures are entirely translucent, which gives them a built-in camouflage.

Since they are cautious and peaceful fish, it is best to keep them in a group of six or more to provide them with a sense of safety.

Fancy Goldfish

Fancy Goldfish are peaceful, but sometimes they are curious. They may eat other species in your tank if their mouth can accommodate it. 

Clown Loach

These Loaches are playful and peaceful and prefer to live in groups. They may grow over typical sizes, so ensure the tank size is optimal for them.

They rummage for snacks at the bottom of the tank and low water column part. 

Bristlenose Plecostomus

The Bristlenose Plecos are calm, friendly creatures that get along well with many other fish species.

These creatures can withstand other curious species in the community tank thanks to their protected scales. 

They are mainly herbivorous and excellent algae eaters, but sometimes you can provide them with bloodworms. 

Boesemani Rainbowfish

If you want to add colors to your tank, it’s a good idea to introduce some Boesemani Rainbowfish. 

These creatures are well known for their peaceful nature and ability to control algae overgrowth.

Pearl Gourami

Besides Boesemani Rainbowfish, the Pearl Gourami is a stunning addition to any aquarium. 

These creatures are relatively peaceful, but male Gouramis may sometimes be territorial toward other members of their species, especially the males. 

Zebra Danio

These aquatic creatures are friendly and love shoaling in groups of six or more. However, they are social and sometimes curious about their tankmates. 

They won’t disturb other species seriously, but they may check them out and nip at their fins if they get stressed. 


Mollies will be the ideal option if you seek hardy creatures that can quickly multiply in your aquarium.

These creatures may sometimes nip at fins. However, they often swim near the surface of the water. Thus, these loaches won’t interact with them much. 

Green Swordtail

These tiny fish are easily reproducible livebearers. Platies and Green Swordtails may interbreed because of their strong relationship.

You can watch this video to know more about the breeding of these two species:


These creatures thrive in groups of at least three female Green Swordtails for one male because males often battle over the chance to reproduce.

Will Yoyo Loaches Eat Tetras?

The short answer is yes! Yoyo loaches can attack, kill, and eat your Neon Tetras due to their tiny size. 

Therefore, if you want to keep these species in the same tank, you should opt for larger Neon Tetras. 

Can You Keep 2 Yoyo Loaches Together?

The answer is no. It’s best to keep a small group of at least six loaches in your aquarium. 

These creatures often show their dominance, which causes them to bully each other. Keeping them in a group of 6 can distract from this natural behavior. 

Will Yoyo Loaches Eat Mystery Snails?

Yes! Loaches will attack the snails, biting at anything they can find until these crawlers stay inside their shell and die of starvation.

Will Loaches Eat Shrimp?

If you plan to add shrimp in your aquarium containing Yoyo Loaches, it’s not a good idea. 

These fish will flip and rip the large shrimp to turn them into a fancy meal. 

Do Yoyo Loaches Eat All Snails?

The bad news is yes. These creatures will kill and eat almost all snails, including pest crawlers. Thus, don’t keep them with these invertebrates.

Wrapping Up

Is Yoyo Loach aggressive? These aquatic creatures are hostile to many other species and the members of their genus in a community tank. 

Therefore, remember to know their ideal tank mates before introducing any creature to your aquarium. 

You can generally keep Yoyo Loaches with Mollies, Pearl Gouramis, Glass Catfish, or Bristlenose Plecostomus.
