🐠 Similar Damsel (Pomacentrus similis)
🐠 Similar Damsel (Pomacentrus similis)
A Blue-to-Grey Body With Subtle Darker Markings • Named for Its Close Resemblance to Other Pomacentrus Species • A Hardy, Geographically Restricted Damselfish
📋 A fun fact about this species' name: "similis" is Latin for "similar," and this damselfish is named for its close resemblance to several other Pomacentrus species, making it a real identification challenge even for experienced aquarists.
The Similar Damsel has an understated blue-to-grey body with subtle darker markings, typical of the broader Pomacentrus genus. It comes from the Indian Ocean, known specifically from Sri Lanka and the Andaman Sea, making it a somewhat geographically restricted damselfish. Every Similar Damsel we ship is feeding well.
This is a hardy, easy-to-care-for species best kept in small odd-numbered groups in a suitably sized system with numerous hiding places. It can be confrontational toward tankmates, and like most damsels, becomes very difficult to catch once established without removing rock from the tank. It's fully reef safe toward corals and invertebrates. It reaches up to 7cm, so a 115L tank suits it well.
