Cleanup Crew
A good cleanup crew is essential for a healthy reef tank. These invertebrates eat algae, detritus, and leftover food to maintain water quality.
Shrimp
Shrimp add color, interest, and utility to reef tanks. From parasite-eating Cleaner Shrimp to Aiptasia-eating Peppermint Shrimp, they serve many roles...
Crabs
Crabs can be valuable cleanup crew members, but some species may become problematic. Choose carefully for your reef tank.
Sea Stars & Starfish
Sea stars add unique interest to reef tanks. While some are excellent cleanup crew members, others may eat coral or prey on fish.
Sea Urchins
Sea urchins are excellent algae grazers that can tackle hair algae and keep rockwork clean. They do tend to redecorate!
Tridacna Clams
Tridacna clams are stunning reef inhabitants with iridescent mantles. They require high light and stable water parameters.
