This starfish is absolutely stunning. It has been in my 150-gallon reef tank for three months and looks more vibrant than ever. The crimson arms move gently with the current, adding a lot of visual interest. I appreciate its peaceful nature and how it doesn’t interfere with other inhabitants. Only thing to note is that it needs stable water parameters and a mature system to thrive.
Audrey Short –
A true centerpiece in my tank. The size is larger than expected, and it blends well with the coral formations. I’ve had it for six weeks now and it’s still active and healthy. The feeding behavior is subtle but fascinating to watch. I’m very satisfied with the purchase and would recommend it to other reef keepers with experience.
Justin Vance –
Beautiful and unique. It’s a bit shy at first, but settles into the tank after a week. I keep it in a low-flow area and monitor water parameters closely. It’s not a high-maintenance species, but it does need a well-established tank. Overall, a great addition to a mature reef setup.
