This starfish has become the centerpiece of my 120-gallon reef tank. It’s stunning in appearance and very calm. I’ve had it for six months and it’s thriving. The arms move gently with the water flow, and it doesn’t seem to interfere with other corals.
Charles Brown –
A beautiful addition to my expert-level aquarium. The red coloration is vibrant and the starfish is active but not aggressive. I appreciate the detailed care notes included. It’s a rare and elegant species that really stands out.
Ryan Terry –
The XL size is impressive and it looks natural in the tank. I’ve noticed it feeds on plankton and doesn’t cause any issues with the coral community. A bit more research on water parameters would have helped, but overall a great purchase.
