Distribution and habitat

The Ogilbyina queenslandiae is found exclusively (endemic) on the coast off Queensland (Australia). They live there on reefs in coral or rock hiding places as well as in self-dug caves in 10-20 m depth.

Maintenance

They require a well-structured aquarium with a reef structure that allows for territoriality (shelters, crevices, caves, branching coral sticks) and live stones that act like a biological filter, as well as fine-grained sandy areas. Only lime-rich, heavy metal-free sands, gravels, stones or sea sand of various grain sizes may be used as substrate

Filters, skimmers and heaters are necessary to ensure water quality, as well as pumps to simulate tides, swells and bottom currents. Lighting must correspond to the species-appropriate day-night rhythm of the animals

Salinity: 33-36 ‰ pH value: 8.1-8.4
Carbonate hardness: 8-10 °KH Nitrate content: 2-8 mg/l
phosphate content: 0.01-0.1 mg/l nitrite content: 0.0-0.05 mg/l

For salinity, an average value should be aimed for, which may only vary slightly by +/- 0.5 ‰. Ammonia and ammonium must not be measurable. Special attention must be paid to consistently good water quality and water values.

Diet

They are ambush hunters that prefer to eat planktonic small crustaceans. The food change usually succeeds without problems. The food supply should consist of a combination of live and frozen food, such as artemia, mysis, shrimp and krill, with chopped fish, mussel and shrimp meat or a commercially available frozen food mixture enriched with vitamins. Dry food (flakes, granules) is rarely accepted

It is recommended to feed small portions several times a day. Regular and varied feeding promotes health and increases resistance.

Behaviour and compatibility

They are very territorial and even in pairs each animal often occupies its own territory, which is vigorously defended. Keeping them in groups is only possible in a larger aquarium with many hiding places. To avoid territorial fights, they should be put into the aquarium at the same time. Towards other fish they behave mostly peacefully.

Sex dimorphism

They are protogynous hermaphrodites, which means that most males develop from functional females when needed. The male has a red head with a dark body, the females have a yellow-orange chest region and a reddish base coloration.

Reproduction and breeding

There are no known reports of successful breeding in the aquarium.

Important

They hardly swim in the open water, but stay close to their hiding place, to which they retreat in a flash in case of danger. As reef dwellers, they should be kept together with corals and not in a fish-only aquarium. Care should be taken when keeping them with shrimp, as they may be considered prey

If different species are kept together, care should be taken to ensure that the fish match each other in terms of water quality and temperature requirements and social behavior, and that the setup meets the needs of all species kept together. New fish to be introduced must be acclimated slowly to the water in the aquarium
