Yellowtail Damsel

About this fish

Yellowtail Damsel is a damselfish for the home saltwater aquarium. The verified scientific name for this fish is Chrysiptera parasema. As an active, hardy marine species, it’s commonly used to add movement and color to reef and fish tanks, and it can coexist with many corals when chosen and managed appropriately.

Features:

• Damselfish (including this species) are often tough and active, making them a popular choice for established saltwater setups.
• Reef compatibility is generally considered good with corals, though like many damselfishes, individual tank behavior can vary.
• As they mature, damsels may become territorial, so plan tankmates carefully and provide ample live rock for claiming space.
• A calm acclimation helps reduce stress—introduce slowly and give the fish a quiet settling spot after arrival.
• Diet is flexible: offer small frozen foods and quality flakes or pellets, typically once or twice per day.
• Good structure and hiding places support natural behavior and can reduce aggression in mixed tanks.
