Genus
Common name: Red Knob Sea Star
Scientific name: Leiaster
Leiaster is a genus of sea stars commonly found in the Indo-Pacific region, known for their striking appearance with bright red knobs or spines. They are popular in the reefkeeping hobby for their vibrant colors and interesting behavior. These sea stars require a well-established aquarium with plenty of live rock to scavenge on and can help control algae growth. They are generally peaceful and can coexist with a variety of tank mates. However, they should be monitored as they can sometimes disturb small-polyped stony corals and sessile invertebrates.
