Similar Damselfish

Greek Name: Pomacentrus similis



Like the popular Yellowtail Damselfish, Pomacentrus similis looks like an electric blue jewel of the aquarium with a beautiful yellow tail. This color combo looks stunning against any background of live rock and corals. What is most appealing to aquarists is the fact that this Similar Damsel is less aggressive and doesn’t require as big of an aquarium space as some Damsels.

Originating from the coral reefs of the Maldives this member of the Pomacentridae family is a fan of multiple hiding areas and calm tankmates. While most Similar Damselfish disregard the other species of fish, invertebrates, or corals, a few may be territorial toward their own kind. This Similar Damsel is best kept in small groups of odd-numbered fish in a suitable size system.

The Similar Damsel requires a 30-gallon or larger tank that has numerous hiding spots. It may be aggressive toward its tankmates.

The diet should comprise different meaty dishes, herbivore dishes, and flaked food items.
