Adult animals of Pomacentrus baenschi inhabit coastal and offshore coral reefs at depths divers can easily reach.
Examinations of the stomach contents of this species revealed the secret of their diet, which contained stomachs:
Zooplankton (22%), benthic algae (53%), sedentary invertebrates (19%) and vagrant invertebrates (4%).
The body of the damselfish is bluish in colour with an orange-yellow part that runs from the forehead to the end of the dorsal fin.
The body is covered with silver-blue spots and forms two lines on the dorsal fin.
The caudal fin is also orange-yellow.
A black spot is sometimes present behind the back under the dorsal fin.
The nose and eyes, whose iris is yellow, are interrupted by thin blue lines.
Some animals have black spots on the edge of the dorsal fin.
We do not have any experience of keeping reef perch at the moment.
