Pomacentrus auriventris

Datasheet

General Description

The Goldbelly damsel, scientifically known as Pomacentrus auriventris, is a member of the Pomacentridae family. This species showcases a striking yellow belly and can grow up to a maximum size of 5.0cm. Found in the Western Central Pacific region, specifically from Micronesia to Indonesia, these fish change color when frightened, typically turning pale or brownish, and may lose their vibrant hues in captivity.

Aquarium Suitability

Goldbelly damsels are deemed suitable for most aquarium setups, but caution is advised due to their aggressive nature towards similar species. They thrive in tanks with good hiding spots like live rocks and necessitate a minimum tank size of 100 liters.

Demands, Care, and Hardiness

This species, known for its hardiness, requires stable water conditions with a pH range of 8.1-8.4, a specific gravity between 1.020-1.025, a temperature range of 22.2-25.6°C, and a carbonate hardness of 8-12 dKH. When housed in an aquarium, providing a varied diet rich in high-quality pigment sources like small crustaceans (such as krill, mysis, and artemia) and zooplankton (like cyclops and pods) can help maintain their coloration.

Reef Suitability

Goldbelly damsels are considered reef-safe and can be suitable additions to a reef aquarium setup. Their territorial behavior may lead to aggression towards other fish that encroach upon their territory, particularly when they have a designated hiding place or during breeding periods.

Aquarium Setup

For optimal care of Goldbelly damsels, it is recommended to set up the aquarium with ample hiding spaces, including live rocks or hollow stones. These fish prefer having their own territory and may exhibit aggressive behavior towards other tankmates, especially if they feel threatened or during breeding times. Providing a suitable environment with hiding spots can help mitigate confrontations among inhabitants.

Behaviour

Goldbelly damsels are known for their territorial nature and aggressive tendencies towards most approaching fishes, particularly those of similar species. To avoid conflicts in the tank, it is advisable to keep only one Goldbelly damsel per aquarium or opt for a large tank where multiple territories can be established.

Feeding and Diet

In captivity, Goldbelly damsels thrive on a diet consisting of small crustaceans like krill, mysis, and artemia, as well as zooplankton such as cyclops and pods. Feeding them multiple times a day with high-quality foods rich in pigment can help maintain their health and vibrant coloration.

Habitat and Distribution

Goldbelly damsels are native to the East Indian Ocean, particularly found in regions spanning from Micronesia to Indonesia. These fish are commonly reported in areas ranging from Micronesia to Indonesia and have been observed as far as Christmas Island in the Eastern Indian Ocean.
