How many dwarf angelfish can be put in a 120 galoon tank?

The number of dwarf angelfish that can be put in a 120-gallon tank depends on several factors, including the species of dwarf angelfish and the size of the individuals. Generally, it's recommended to only keep one dwarf angelfish in a 120-gallon tank, as they are territorial fish and may become aggressive towards each other if kept together. However, some species of dwarf angelfish, such as the Coral Beauty Angelfish (Centropyge bispinosa) or the Flame Angelfish (Centropyge loricula), can be successfully kept in pairs or small groups if the tank provides enough swimming space and hiding places.

Here are a few guidelines for keeping dwarf angelfish in a 120-gallon tank:

- Start with a single dwarf angelfish: This is the safest option, as it minimizes the risk of aggression. If the fish is healthy and thriving, you can consider adding a second dwarf angelfish after some time.

- Choose compatible species: If you decide to keep more than one dwarf angelfish, select species that are known to be compatible with each other. Some dwarf angelfish species are more aggressive than others, and mixing incompatible species can increase the risk of aggression.

- Provide plenty of swimming space: Dwarf angelfish are active swimmers, so they need plenty of space to move around. A 120-gallon tank is a good size for one or two dwarf angelfish, but it may feel crowded if you try to keep more than that.

- Create hiding places: Dwarf angelfish appreciate having places to hide, especially when they are feeling stressed or threatened. Provide some live rocks, caves, or other decorations that the fish can use for shelter.

- Feed a varied diet: Dwarf angelfish are omnivorous, so they need a varied diet that includes both meaty foods (such as brine shrimp or mysis shrimp) and plant-based foods (such as algae or Spirulina flakes).

By following these guidelines, you can successfully keep dwarf angelfish in a 120-gallon tank and enjoy their beautiful colors and fascinating behaviors.
