Distribution and habitat

Lobophyllia hemprichii belongs to the group of LPS (Large Polyp Scleractinia). This reef-building coral is widely distributed in the tropical Indian and Western Pacific Oceans. It occurs  in different colors on protected reef slopes, in partly large colonies

Maintenance

They should be positioned in a place with high to medium light intensity and moderate, alternating current. Only high-calcium, heavy metal-free substrates should 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. 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, which are unicellular symbiotic algae, live in their tissues and provide them with assimilation products of their photosynthesis (high light intensity). The zooxanthellae promote growth and provide additional food to the plankton and small particles, which are collected in large quantities from the water current. Thus, in addition to the food produced in the aquarium during fish feeding (mysis, krill, Artemia, etc.), commercial supplementary food in the form of phyto- and zooplankton should be offered regularly

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 must be kept from cnidarians.

Reproduction and breeding

Sexual reproduction is not known. In the aquarium they can be propagated in a limited way by fragmentation. Damage to living tissue can lead to the death of the entire colony.

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

Lobophyllia grow in colonies with large, sometimes unseparated polyps and can form large monotypic fields. They occur in different colors (red, green, yellow) mostly fluorescent. The additional illumination with actinic light (short-wave, violet-blue light) is very beneficial for their growth (zooxanthellae). A calcium reactor and a magnesium dosing pump are recommended for the necessary uniform 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 acclimated 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
