Lighting Soft corals prefer low light levels of 25–75 PAR, so you don't need a high-output light.
Water chemistry Soft corals can tolerate changes in water quality and chemistry, and they need a salinity of 1.025 or 35 ppt.
Water exchange You should regularly exchange the water in your tank. Some recommend changing the water once a week with high quality salt.
Flow Soft corals prefer low indirect water flow, but a moderate current can help circulate food across them.
Temperature Soft corals prefer a temperature of 72–76°F (22–24°C).
Diet Soft corals like regular feeding of small particle, plankton size foods, such as live zooplankton and phytoplankton.
Soft Corals - What are the Best Foods to Feed them Zooplankton and Phytoplankton: Soft corals feed on microscopic organisms like live zooplankton and phytoplankton in their natural habitat. Replicating this diet in your home aquarium is crucial for their growth and health.
Soft corals are photosynthetic marine invertebrates that lack a rigid skeletal structure. Most soft corals anchor onto rocks directly and will be placed in the lower half of the tank. Some types of soft corals, like green star polyps (GSP), require a moderate to a high amount of flow and a moderate amount of light.
