sucker fish

Description:

They are extremely popular in aquaria for their ability to clean tanks by eating algae growth and dead fish. In Malaysia, these fish are called 'ikan bandaraya' or 'municipal fish' in English because of their ability to clean fish tanks. These friendly-natured fish can typically be purchased when about 8 cm (3 inches) and may grow up to 60 cm (2 ft) if there is adequate room, making them mostly impractical for any but the largest aquariums.

Habitat:

They live in tropical fresh water.They have been found in ponds. In South America, they can be found everywhere. In an aquarium setting these fish find great pleasure in air stones and swimming in and through the bubbles

Notes:

There are many types of suckermouth armoured catfishes that science has not described. As a result, they are given a common name and an L-number designation until a new scientific name for the fish is described. An example is the flash plecostomus, L204, believed to be a species of Panaque.
