Reef Cleanup Crew
Build Your Perfect Reef Cleanup Crew
A cleanup crew is one of the most important investments you can make for a healthy reef tank. These hardworking invertebrates work around the clock to control algae, consume detritus, aerate your sandbed, and keep your tank looking its best — all while adding fascinating life to your aquarium.
Why Every Reef Tank Needs a Cleanup Crew
-
Algae control — Snails and crabs graze on nuisance algae before it takes over your rocks and glass
-
Detritus removal — Nassarius snails and hermit crabs break down uneaten food and waste, reducing nutrient buildup
-
Sandbed health — Burrowing species aerate and turn your sand, preventing dead zones and hydrogen sulfide buildup
-
Natural balance — A diverse crew mimics the natural reef ecosystem, reducing your dependence on manual maintenance
How Many Do You Need?
A general rule of thumb is 1–2 snails and 1 hermit crab per gallon of water. A diverse mix of species is more effective than large numbers of a single species, as different animals target different types of algae and waste.
