Distribution and habitat
The range of Koumansetta rainfordi extends from the south of the Philippines to the Great Barrier Reef and from Indonesia to Tonga. They live in sheltered sandy lagoons and on inner reefs where they like to stay under large coral reefs up to 20 m depth.
Maintenance
They need an aquarium with a reef structure that offers numerous hiding, resting and covering possibilities, with living stones that act like a biological filter and free sand areas with a graveable, at least 6 cm deep substrate of fine to medium coral sand
Only calcareous, 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 constantly good water quality.
Diet
In nature they feed mainly on zooplankton and algae. The food change does not always succeed without problems. The food supply should consist of a combination of live and frozen food, such as small mysis, artemia, bosmids and cyclops, or a commercially available vitamin-enriched frozen food mix for planktivores. In addition, they need plenty of algae as food (nori algae). High-quality flake and granulated food on a vegetable basis (spirulina, kelp) is also often accepted after a period of acclimatization. It is recommended to feed small portions several times a day. Regular and varied feeding promotes health and increases resistance.
Behaviour and compatibility
They can be kept singly or better in pairs. Internally they behave territorially, so keeping several pairs is only recommended in a much larger and richly structured tank. They can be well socialized with other, not too lively fish.
Sex dimorphism
There are no known external distinguishing characteristics.
Reproduction and breeding
There are no known reports of successful breeding in the aquarium.
Important
They eat the algae growth and sift the sand for microorganisms. Some also pluck at filamentous algae
The aquarium should be well covered, because they are skittish and like to jump.
If different species are kept together, make sure that the fish match each other in terms of water quality and temperature requirements, as well as their social behavior, and that the setup meets the needs of all species kept together. Newly introduced fish must be acclimated slowly to the water in the aquarium
