The Yellowtail Damsel (Chrysiptera parasema) is a colourful, hardy and popular marine fish recognised by its brilliant electric-blue body and contrasting bright yellow tail.
It is one of the better choices for aquarists wanting a damselfish without the extreme aggression associated with some other damsel species. Their durability, manageable size and willingness to accept a wide range of foods also make them a great option for newer marine fish keepers.
Aquarium Care
Yellowtail Damsels are hardy fish that adapt well to a variety of established marine aquariums.
Provide plenty of live rock, caves and hiding places, allowing the fish to establish a territory and retreat when required.
While generally less aggressive than many other damselfish, they can still become territorial, particularly towards their own species or similarly sized fish. Providing plenty of space and rockwork can help reduce territorial disputes.
They can be kept individually or in appropriately sized aquariums with compatible tankmates.
Feeding
Yellowtail Damsels are omnivorous and usually enthusiastic feeders.
Offer a varied diet including:
-
Quality marine pellets
-
Marine flakes
-
Frozen mysis shrimp
-
Enriched brine shrimp
-
Frozen marine blends
-
Algae-based foods
Providing a mixture of meaty and vegetable-based foods will help maintain strong colour, condition and overall health.
Reef Compatibility
The Yellowtail Damsel is considered reef safe and will normally leave corals and ornamental invertebrates alone.
Their small size and vivid colour make them particularly attractive against live rock and coral displays.
Why We Like Them
Yellowtail Damsels offer a lot of colour for a relatively small fish.
They're hardy, active, affordable and easier to manage than many more aggressive damselfish, making them a strong choice for both beginner marine aquariums and established reef systems.
Their intense blue body and yellow tail also make them stand out exceptionally well under reef lighting.
