There are many different aquarium animals that will clean algae off the walls of your aquarium. I will name a few: Cories, Plecostomus (AKA, Pleco) and more. There are some algae eaters that are not fish. Mystery snails, freshwater snails, and other water snails eat algae. Ghost shrimp are small and are very easy to take care of. They clean the decorations in your fish tank and eat any uneaten, leftover food.
the answer is sucker fish or catfish sucker fish
Plecostamus
Scoop all your fishes to another tank or tub of water and clean the fish tank just as you would normally without the fish
Other fishes
You may be referring to a "Cleaner Wrasse"
