I bought this green brittle starfish for my reef tank. It’s active at night and has been eating small crustaceans without harming the larger fish. The water parameters are stable and it adapts well to the tank conditions. I’m happy with the beginner-friendly care requirements.

The starfish arrived healthy and has been active since setup. I noticed it hunting at night, so I removed a small shrimp that was too small. It’s not aggressive toward larger fish, and the lighting and temperature are within recommended ranges.

It’s a unique addition to the tank. I had to adjust the pH slightly to match the recommended range. It’s not a good fit for small fish, but it’s fascinating to watch at night.
