Distribution and habitat
The range of Sarcophyton glaucum is the Indo-Pacific, where they are widely distributed from the Red Sea through Indonesia and Australia to Taiwan, the Ryukyu Islands and Palau. They live in shallow water of well flowed lagoons with muddy bottoms and often form large colonies.
Maintenance
They should be positioned in a location with moderate to high light intensity and moderate to strong 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: 8-12 °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 iodine 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 collected from the water current. In addition to the food produced in the aquarium during fish feeding (mysis, krill, artemia, etc.), commercial food for lower animals in the form of phyto- and zooplankton, frozen or liquid, should be offered regularly
Regular and varied feeding promotes health and increases resistance.
Behaviour and compatibility
They live both solitary and in colonies and can be well socialized with fish that do not consider them food. A sufficient distance to other corals must be kept, in order not to restrict them in their growth and to avoid a nettling.
Reproduction and breeding
They are separately sexual. The larvae are part of the plankton for several weeks until they settle in a suitable place. Reproduction by forming daughter colonies (budding) is also possible. In the aquarium they can be propagated well by fragmentation (separation of tissue parts). The fragment is fixed on a piece of living rock, to which it grows firmly after a few weeks.
Important
They "shed their skin" by sloughing off. With their mucus cells they form a thin, greenish shimmering "skin" which is removed by inflating and protruding the polyps in shreds. This removes pollution, such as sediments and algae, but also parasites.
The additional illumination with actinic light (short-wave, violet-blue light) is very beneficial for their growth (zooxanthellae).
For the necessary uniform supply of calcium carbonate and magnesium, a calcium reactor and a magnesium metering pump are recommended.
If different species are kept together, care should be taken to ensure 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. Newly introduced animals must be acclimated slowly to the water in the aquarium.
