Angelfish vs. Guppies: Behavior

The first factor worth considering is the Angelfish’s and Guppies’ natural behavior. Here is what you should know:

1. Angelfish: Natural Behavior

Angelfish, by nature, are semi-aggressive and can exhibit territorial behavior when they mature, especially if they pair off and breed.

In a community tank, they often assert dominance and require space to establish their hierarchy.

  • Territorial Defense: Mature Angelfish typically require at least 20 gallons per fish to establish territories, often showing aggression if this space is encroached upon.
  • Predatory Instincts: Angelfish, which can grow up to 6 inches, may see small fish as prey, especially in tanks smaller than 55 gallons where space is limited.
  • Social Hierarchy: In groups, Angelfish form a strict social order; the dominant fish usually eats first and chooses the prime hiding spots in the tank.

2. Guppies: Natural Behavior

Guppies are sociable, active swimmers and are generally non-aggressive, making them a staple in community aquariums.

They reproduce quickly, which can lead to overpopulation in a tank if not managed.

  • Schooling Behavior: Guppies thrive in groups of five or more, requiring less space with a minimum of 2 gallons per fish, enabling a dynamic and engaging tank environment.
  • Non-Aggressive Interaction: Guppies rarely show aggression; they coexist peacefully with similarly sized and tempered fish, avoiding conflicts within a diverse tank.
  • Rapid Breeding: A pair of Guppies can reproduce monthly, with fry numbers ranging from 20 to 50, necessitating a tank management plan to control population growth.
