Distribution and habitat
Balanophyllia bairdiana belong to the group of LPS (Large Polyp Scleractinia). These non-reef-building corals (ahermatypic) are widely distributed in the western Central Pacific and from the Philippines to southeastern Australia. They occur in different colors according to their species and origin in arboreal branching colonies, mostly under rock overhangs in the lower intertidal zone up to 50 m water depth.
Maintenance
They should be positioned in a place with the lowest possible light intensity and medium, alternating flow. Only lime-rich, heavy metal-free substrates should be used as substrate
To ensure water quality, filters, skimmers and heaters are necessary, as well as pumps to simulate tides, swell and bottom current
It is recommended that live stones be used to set up the aquarium. The bacteria living in the porous stones act as a biological filter. The 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 |
| calcium content: 420-450 mg/l | Nitrite content: 0.0-0.05 mg/l |
| Magnesium content: 1.250-1.350 mg/l | phosphate content: 0.01-0.1 mg/l |
Regular addition of trace elements, especially calcium and strontium, is recommended. 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 shall be paid to consistently good water quality and water values.
Diet
Zooxanthellae (azooxanthellate) do not live in their tissues. Therefore, in addition to the food that accumulates in the aquarium during fish feeding (mysis, krill, artemia, floating shrimp, etc.), they are regularly dependent on supplementary food in the form of commercially available phyto- and zooplankton
Regular and varied feeding promotes health and prevents deficiency symptoms.
Behaviour and compatibility
They should not be kept with fish that regard their polyps as food (e.g. angelfish or butterflyfish). They are well tolerated with other corals, but sufficient distance from cnidarians must be maintained. They are sensitive to touch.
Reproduction and breeding
Reproduction occurs through the formation of daughter colonies (brooders).
Species protection
Species protection: WA Appendix II; EU Appendix B. The proof of purchase is the required proof of origin for the animal. Please keep it safe! Your pet store will be happy to provide you with further information.
Important
They belong to the group of azooxanthellate corals and can therefore also colonize biotopes without sunlight. Some species of these corals are also found in the Mediterranean and the North Atlantic at depths of up to 1,600 meters
A calcium reactor and a magnesium dosing pump are recommended for the necessary even supply of calcium carbonate and magnesium. Too high temperature, insufficient lighting or current as well as sudden change of water values can lead to tissue decay (RTN - rapid tissue necrosis). When purchasing, look for pressure marks or other tissue damage. Newly introduced animals must be accustomed slowly to the water in the aquarium
If different species are kept together, make sure that fish and invertebrates match each other in terms of water quality and temperature requirements as well as their social behavior, and that the setup meets the ecological needs of all species kept together
