I added the Chocolate Chip Starfish to my 50-gallon reef tank and it has been very calm and active. It spends most of its time grazing on the sand bed. The appearance is unique and adds a nice visual element. I appreciate how easy it is to care for and how it doesn’t stress other tank inhabitants.

The starfish arrived healthy and looked exactly as described. It’s peaceful and doesn’t seem to be aggressive. I’ve noticed it moving slowly across the sand, which is quite fascinating. I keep the water flow moderate, and it seems to be adjusting well.

This is a great addition to a beginner’s tank. It’s not flashy, but it’s charming and adds a natural look. I’ve had it for a few months now and it’s still active and healthy. The dark nodules are very distinctive and make it stand out.
