Are Angelfish Schooling Fish?

No. Angelfish are not schooling fish. Angelfish form loose aggregations in the wild, swimming together in small groups. These aggregations are more tightly organized than traditional schooling fish, but they do showcase a degree of social behavior. 

Now, feel free to wonder how Angelfish interact within their groups. Like any community, our little friend, ‘angelfish,’ has social hierarchies. In addition, if you notice these small groups of Angelfish closely, you can observe dominant individuals and their subordinates.

Don’t take this lightly because these hierarchies are vital in maintaining order and minimizing aggression. Also, you should know about research conducted by Luis M. Gómez-Laplaza who observed Angelfish in their natural environment.

They have successfully found that dominant Angelfish tends to exhibit more assertive behavior and may even influence the feeding & breeding activities of the group. It has also been found that dominant Angelfish tend to lead the group during foraging expeditions and are more likely to initiate social interactions.

You should know that these graceful creatures call the Amazon River basin their home and are found in various waterways across South America. Interestingly, Angelfish are predominantly freshwater fish, although a few species can also adapt to salty water.

Benefits of This Schooling-Type Behavior

Now, let’s talk about the advantages of schooling behavior for Angelfish. While their social structure may not be as cohesive as typical schooling fish, there are still notable benefits to swimming in small groups.

Increased Protection Against Predators

By staying in numbers, Angelfish can gain additional protection against predators. They usually swim together by farming loose aggregations to potentially confuse and make it harder for the predators to target an individual fish.

From a distance, predators often miss aiming individual Angelfish as Angelfish gets a chance to escape when any spot predator approaches them, increasing their chances of becoming prey.

Improved Foraging Efficiency

You should know that Angelfish carry a territorial streak that sets them apart from traditional schooling fish. In The wild, they have evolved to establish and defend their territories, which may explain their preferences for a more solitary or pair-based lifestyle.
