Care
Plectranthias inermis is a hardy species that adapts well to life in captivity. It requires a well-established aquarium with plenty of live rock for hiding and hunting. This fish is a carnivore and thrives on a diet of small meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood. It is important to maintain high water quality and stable parameters to keep this fish healthy.
Reproduction
In the wild, Plectranthias inermis is known to spawn in small groups, with males displaying to attract females. In the aquarium, breeding is rare, but with the right conditions and a mature pair, spawning may occur. The eggs are pelagic, meaning they float in the water column until hatching.
Habitat
The Geometric Pygmy Hawkfish is found in the Indo-Pacific region, typically in coral-rich areas and on reef slopes. They prefer depths ranging from shallow waters to about 90 meters. In the aquarium, they do not require a large space, making them suitable for smaller reef tanks as well.
