Distribution and habitat

Sabellastarte spectabilis are widely distributed from the Red Sea and the Indo-Pacific to the coast of Central America. They live in self-made, parchment-like living tubes and settle on different substrates up to a depth of 15 m on the coral reef.

Maintenance

They should be carefully wedged between stones or buried at an angle in the substrate in a location with low light and low current. Stony corals as co-inhabitants in the aquarium are advantageous

Only substrates rich in lime and free of heavy metals may be used as substrate. To ensure water quality, filters, skimmers and heaters are necessary, 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 calcium, 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

In nature they feed on microplankton and detritus. Even in a well acclimated aquarium, additional feeding is usually unavoidable. They should be fed directly and specifically (pipette) several times a week with Artemia nauplii, Cyclops, lobster eggs as well as zooplankton and live phytoplankton, which is available as ready-made food in specialized shops.

Regular and varied feeding promotes health and prevents deficiency symptoms.

Behaviour and compatibility

They can be well socialized with fish and lower animals that do not consider their polyps food (e.g., angelfish or butterflyfish).

Reproduction and breeding

Little is known about reproduction. They produce male and female gametes simultaneously, which are released into the surrounding water. Reports about successful reproduction in the aquarium are not known.

Important

In their wide range there are numerous differently colored animals. An exact determination on the basis of the tentacle crown is not always possible.

During transport and relocation care must be taken that no air gets into the tube

If disturbed, they retreat into their tube as fast as lightning. Under unfavorable husbandry conditions (stress situation, lack of food) the tentacle head can be thrown off. However, healthy animals soon regenerate it. It can also happen that they leave their living tube to build a new one in a few hours or days.

Newly introduced animals must be acclimated slowly to the water in the aquarium. If different species are kept together, care must 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
