Saltwater Aquarium Cleaner Fish. Probably the most common and the one pictured above is the Neon Blue Goby Theyre generally pretty peaceful and even provide a parasitic cleaning service if you have any larger reef fish in the tank. These little guys can be put in tanks as small as ten gallons.
Six Line Wrasse. The only downside is that they can be difficult to care for. No saltwater water clean up crew should be without hermit crabs.
Surgeon fish rank as a common saltwater aquarium cleaner fish.
It can also host hordes of little organisms like copepods and rotifers. These fish are hardy and peaceful. But this fish doesnt have parasites in mind. Snails are super cleaners.
