yes they do

Mickey mouse fish are very clean
The scientific name for cleaner fish is "Labridae." Cleaner fish are known for their symbiotic relationship with other marine species, where they clean parasites and dead skin off larger fish.
The only "Cleaner fish" that I know of is the Marine species called the "Cleaner Wrasse". These fish pick parasites off other fish and will even swim into larger fishes gills and mouths to clean them too. If you are thinking of Catfish as being cleaner fish, then you have got things very wrong. Catfish are bottom dwelling fish but they do not clean up dirt and rubbish. They need fresh food just like any other fish. To the best of my knowledge no species of fish do well in a dirty tank.
All fish have the ability to have a smaller fish attach to them. There are two different types of cleaner gobies that attach to small fish to clean them. Then there are five different species of larger fish that tend to clean larger fish such as sharks.
Sharks do not necessarily need sucker fish, or cleaner fish, to stay clean, but these relationships can be beneficial. Cleaner fish, like remoras, eat parasites and dead skin off sharks, helping to maintain their health. While sharks can manage their hygiene on their own, the presence of cleaner fish can enhance their overall well-being. This symbiotic relationship is an example of mutualism, where both species benefit.
No catfish is an aquarium cleaner. There is no such thing as a fish that will clean a tank.
The comparative form of "clean" is "cleaner."
Larger fish sometimes have smaller fish who clean the algae and parasites from their scales and gils. Smaller fish will rub themselves against the gravel, sand or against rocks to clean their scales.
To clean a fish tank glass, you can use a non-abrasive sponge or a special aquarium glass cleaner. Avoid using harsh chemicals or abrasive materials that can harm your fish or the tank's ecosystem.
The syllabication of "cleaner" is "clean-er."
