Biology and life history (FishBase)

Measured values published by FishBase for Chrysiptera starcki. Only fields the database actually holds for this species are shown; these are database values, not aquarium guidance.

Maximum length: 7 cm · Depth range: 20–60 m · Habitat zone: reef-associated · Body shape: fusiform / normal · Vulnerability index: 10 of 100.

FishBase notes: Adults inhabit rocky outcrops and crevices that are frequently situated in sand channels on outer reef slopes. Common in deeper sections of the outer reef about 20 to 60 m in depth (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205).

Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).

Description and natural history (Wikipedia)

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.

Starck's demoiselle is blue with a yellow stripe down its back. It grows up to 7 cm in length.

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

When breeding, males will swim back and forth swiftly flashing their colors to attract females. Males will prepare a territory full of rubble for the female to lay her eggs. Then the male will fertilize them and aggressively defend them from intruders.

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. 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.
