The specific name honours the marine biologist Walter A Starck II who pointed out this species out to Gerald R. Allen while diving with him at Osprey Reef in the Coral Sea.^[3]

Starck's demoiselle is blue with a yellow stripe down its back. It grows up to 7 cm (2.8 in) in length.^[2]

The fish lives around reefs, often in deeper, outer areas, up to 60 m (200 ft) deep. It lives in crevices in rocky areas. It pairs up to breed and the male guards and tends the eggs.^[2] In the wild, Starck's demoiselle will eat plankton (both zooplankton and phytoplankton).^[4]

This is a highly desired fish for a saltwater aquarium. Shallow waters are best for the fish. It can be very colorful if fed the correct diet. The minimum aquarium size is 76 L (20 US gal).^[5] The tank should be decorated with rocks or gravel and should have many hiding places for the fish. It is not a very aggressive fish, but as it gets bigger it may harass smaller, more passive fish. Two of them together in a tank will fight, however. They are very easy to keep in captivity. They will eat many different types of foods in captivity.^[4][6]
