• Swimming Space: While they enjoy exploring rocks and crevices, they are active swimmers and need ample open swimming space.

Water Parameters:

• Temperature: 72-78°F (22-26°C)

• pH: 8.1-8.4

• Salinity: 1.023-1.025 specific gravity

• Hardness: 8-12 dKH

Care Level:

• Difficulty: Easy to moderate. The Yellowtail Damsel is a hardy fish that can tolerate a range of water conditions, making it a suitable choice for both beginner and experienced aquarists.

• Diet: Omnivorous. The Yellowtail Damsel feeds on algae and zooplankton in the wild, but in the aquarium, it will accept a variety of foods, including high-quality pellets, flake foods, algae-based foods, and occasional frozen offerings like mysis shrimp or brine shrimp.

• Behavior: Generally active and somewhat territorial. While they are not overly aggressive, they may exhibit territorial behavior, especially towards other damselfish or similarly shaped species.

Reef Compatibility:

• Reef-Safe: Yes, the Yellowtail Damsel is reef-safe and poses no threat to corals or invertebrates. It may, however, occasionally nip at certain types of algae or small invertebrates.

Tank Mates:

• Suitable Companions: Other peaceful species such as clownfish, wrasses, gobies, and blennies are good companions. It’s best to keep the Yellowtail Damsel in a group of 3 or more individuals to reduce territorial aggression. However, avoid keeping it with other aggressive or territorial species.

• Avoid: Other damselfish or similarly shaped fish unless the tank is large and well-structured to provide plenty of hiding spots.

Additional Tips:

• Schooling Behavior: Though it can be territorial, Yellowtail Damsels often do well when kept in small groups. This helps them feel secure and reduces aggression between individuals.

• Feeding Routine: Provide a variety of foods, including both algae and meaty offerings, to ensure balanced nutrition.

• Water Quality: As with all saltwater fish, maintaining excellent water quality through regular water changes and effective filtration is crucial to the health and longevity of the Yellowtail Damsel.
