Received the starfish in good condition. It’s active and peaceful in the 75-gallon tank. The tank setup was stable and it adapted well within a week. No aggression observed with other fish. A solid addition to a reef tank.

The starfish looks unique and fits well in the tank. It’s calm and doesn’t interfere with other inhabitants. Only needed a bit more space than expected, but still manageable in a 75-gallon setup.

Great choice for intermediate aquarists. It’s visually striking and stays calm. The care instructions were clear and easy to follow. Has been thriving for over two months now.
