Sinularia sp. - Corals for beginners in marine aquarium keeping
In contrast to stony corals, soft corals do not form a solid skeleton made of calcium carbonate. They are therefore more tolerant of fluctuations in calcium concentration and KH values. Soft corals are perfect candidates for both beginners in reef aquarium keeping and for aquarists who do not (want to) pay meticulous attention to their water values.
Why do soft corals like Sinularia sometimes show no polyps?
Many soft and leather corals "shed their skin" at regular intervals. During this time, no polyps are visible and the coral develops a smooth to shiny surface. The Sinularia then needs sufficient current so that the upper layer of tissue, which is used to remove deposits, can be easily removed. The polyps have also retracted a few hours after transport, when moving or at night.
High nutrient values? No problem for soft corals!
Soft corals cope well with increased nutrient concentrations. Phosphate concentrations of up to 0.2 mg/l and nitrate concentrations of up to 20 mg/l are considered perfectly acceptable. They are therefore not only ideal for a newly set up or small reef aquarium, but also for keeping with fish.
