Angelfish vs. Silver Dollars: Behavior

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

Angelfish: Natural Behavior

Angelfish are known for their graceful swimming and somewhat territorial nature, especially during breeding.

They often establish a hierarchy within their group and can show aggression to protect their territory.

  • Territorial During Breeding: Angelfish become more territorial when breeding, often guarding their eggs and fry aggressively against intruders, including other tank mates.
  • Hierarchy Establishment: In a group, Angelfish often establish a social hierarchy, which can lead to some aggression towards weaker or smaller fish in the aquarium.
  • Graceful Swimmers: Angelfish are slow, elegant swimmers, preferring to glide through the water, which can be disrupted in overcrowded or high-energy tanks.

Silver Dollars: Natural Behavior

Silver Dollars are schooling fish known for their peaceful and skittish nature. They prefer to swim in groups and are generally not aggressive, making them good community fish.

  • Schooling Behavior: Silver Dollars thrive in groups and exhibit schooling behavior, which reduces stress and helps them feel secure in the aquarium environment.
  • Non-Aggressive Nature: They are known for their peaceful disposition, rarely showing aggression towards other fish, making them suitable for community tanks.
  • Skittishness: Silver Dollars can be easily startled and prefer plenty of hiding spaces, emphasizing the need for a well-structured tank with ample cover.
