Distribution and habitat
The distribution area of Bodianus diana is the Red Sea and the Indo-Pacific, from South and East Africa to Indonesia and the Marshall Islands. They live on reefs with dense coral growth, juveniles prefer caves and on or next to black corals and gorgonians.
Maintenance
They are keen swimmers and require a well-structured aquarium with plenty of swimming space, a reef structure (hiding and retreat possibilities) with live stones, which act like a biological filter, as well as sand areas, made of fine sand at least 10 cm deep (no coral rubble!). Only lime-rich, heavy metal-free sands, gravels or stones may be used.
Filters, skimmers and heaters are necessary to ensure water quality, as well as pumps to simulate tides, swells and bottom currents. Lighting must be appropriate for the species' day-night rhythm
| 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
Juveniles act as cleaner fish and eat parasites, adults feed mainly on snails, worms, mussels and small fish. The food change usually succeeds without problems. The food supply should consist of a combination of mysis, krill, artemia, smelt, shrimp, mussel and crab meat, or a commercially available vitamin-enriched frozen food mix. High-quality flake and granulated food is also often accepted after a period of acclimation.
It is recommended to feed small portions several times a day. This reduces intra-species aggression and protects lower animals in the aquarium. Regular and varied feeding promotes health and increases resistance.
Behaviour and compatibility
They usually live in a group consisting of females and juveniles, dominated by one male. Males are very territorial within the species. Accordingly, only one male should be kept singly, or with one or more females. Towards other fish they behave peacefully.
Sex dimorphism
They are protogynous hermaphrodites, meaning that most males develop from functional females when needed, and are referred to as "secondary males." External distinguishing characteristics are not known.
Reproduction and breeding
There are no known reports of successful breeding in the aquarium
Important
Their color dress varies greatly depending on age
As reef dwellers they should be kept together with corals and not in a pure fish aquarium. With sufficient and varied feeding, which also reduces aggressiveness, they can be kept well with invertebrates (corals), only tubeworms, snails, crabs etc. should be kept with caution
When threatened, they sometimes bury themselves in the sandy substrate.
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
