what kind of fish is cleaner than in an aquarium?

I have a small tank, so i like fish if any:)

Are you asking "Clean" as in "produces less waste? You want to go with the smaller species. If you are limited in space, for starters, try guppies (all males unless you want you can fry quickly overpopulate your tank), neon, cherry barbs, livebearers Endler, or the smaller danios. With all services under or around 2 ". Danios El, neon, and spikes must be kept in groups of 5-6 +, though, so condis is in Depending on the size of the tank. If something a bit pale t Corydoras different or kuhlii loaches, which should be in groups of about 3 or killifish.
