Easy to care for and very active in the tank. It cleans up dead algae and small debris without disturbing other fish or corals. Great for beginners looking to add a natural cleaner to their reef setup.

The shrimp has been in my 40-gallon tank for three months. It’s peaceful and helps keep the tank tidy. I didn’t expect it to be so hardy, especially in a mixed reef environment.
