Distribution and habitat

Seriatopora spp. belongs to the group of SPS (Short Polyp Scleractinia). This reef-building coral is widely distributed in the tropical Indian and Pacific Oceans, where it occurs in small colonies to depths of 6-25m. It lives on the upper reef slopes, which are protected from strong surf. The picture shows a Seriatopora caliendrum.

Maintenance

They should be positioned in a location with high light intensity and moderate to strong, alternating flow in the middle or upper area

As a substrate, only lime-rich, heavy metal-free substrates should be used. The aquarium should not lack live stones, which act as a biological filter. To ensure water quality, filters, skimmers and heaters are necessary, as well as pumps to simulate tides, swells and bottom currents. 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: 8-12 °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 magnesium 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 tissue and provide them with assimilation products of their photosynthesis (high light requirement). The zooxanthellae promote growth and provide additional food to the plankton and small particles that 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 supplemental food in the form of phyto- and zooplankton should be offered once or twice a week. Regular and varied feeding promotes health and increases resistance.

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

In nature, reproduction is sexual via marine larval stages. In the aquarium they can be propagated well by fragmentation. Fragments are fixed in the reef structure, e.g. with a good two-component coral glue (epoxy).

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

According to their origin, they come in different growth forms and colors. They are fast-growing and very sensitive to changing water conditions.

The additional illumination with actinic light (short-wave, violet-blue light) is very beneficial for their growth (zooxanthellae). A calcium reactor and magnesium metering pump are recommended for the necessary steady 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
