Description
The Green Brittle Sea Star (Ophiarachna incrassata) is a fascinating and resilient echinoderm known for its distinct green to olive coloration and long, slender arms. This species is popular among aquarists for its unique appearance and interesting behavior in the reef aquarium.
Green Brittle Sea Stars are generally semi-aggressive and should be housed with caution alongside smaller or more passive tankmates, as they may exhibit opportunistic feeding behavior. They are known to scavenge and can potentially harm small fish or invertebrates if given the opportunity.
This species requires a well-established aquarium with stable water conditions to thrive. They are omnivores, primarily feeding on detritus, leftover food, and small invertebrates. Providing a varied diet that includes meaty foods, such as shrimp and fish, will help maintain their health.
Green Brittle Sea Stars are known for their ability to regenerate lost arms, which adds an intriguing aspect to their care. They thrive in environments with plenty of hiding spots, such as rock structures and caves, where they can feel secure and hunt for food.
A minimum tank size of 50 gallons is recommended to ensure ample space for foraging and to accommodate their growth, as they can reach sizes of up to 12 inches across.
