Description
The Yellowtail Dascyllus is a hardy and attractive damselfish characterized by its dark body and striking bright yellow tail. While generally peaceful as juveniles, they can become territorial and semi-aggressive as they mature, especially towards smaller or more docile tankmates. They are a popular choice for beginner saltwater aquarists due to their resilience.
