The Yellowtail Blue Damselfish, also known as Yellowtail Demoiselle or Goldtail Demoiselle is good beginner species. It is probably probably one of the most popular fish for beginner setups. It eat a wide range of foods, withstand poor water conditions, is disease resistant and inexpensive. It is confused in naming with the Azure Damselfish (Chrysiptera hemicyanea), which is yellow in the pectoral and anal fins, but not in the tail.
In the wild, it is native to the Western Pacific waters where it can be found in small groups in coral-rich areas of sheltered lagoon and inshore coral reefs at depths of 5 to 52 feet.
The ideal aquarium should have plenty of places to hide and swim. Although Yellowtails are among the least aggressive damsels, they still should be kept either alone or in groups of 4 or 5 in a large tank to reduce aggression. Ideally, pH should be at 8.0-8.4, Specific gravity at 1.020-1.030 and temperature between 73F and 83F.

While perhaps less aggressive than other damsels, it was still more aggressive than I needed for my nano. I gave him to a friend…
How big is your nano? I have 2 in 25 gallon without problem. The fight for the first week so I moved one to an other tank. A week later, I tried to keep them together again and it’s ok now. They swim together and never fight.
To help, I created some new hiding places.
I want to upgrade my tank from a freshwater cichlid tank to a saltwater setup. The fist are so much more colorful. I really like your Damsel fish.
