Hypostomus plecostomus - Mum's lil fishies

Hypostomus plecostomus (known colloquially as a sucker fish) is the scientific name for a type of freshwater tropical Central and South American fish belonging to the family Loricariidae. They are large algae eaters, and to differentiate them from small algae eaters, they are often referred to as plecostomus, often abbreviated as plecos or plecs. They are extremely popular in aquariums for their ability to clean tanks by eating algae growth and dead fish. These friendly-natured fish can typically be purchased when about 8 centimetres (3.1 in) and may grow up to 60 centimetres (24 in) if there is adequate room, making them impractical for any but the largest aquariums.

Plecos are omnivorous but, in the wild, feed nocturnally mostly on plant material. During the day, their unusual omega irises block a lot of light out of their eyes, but they are usually open at night. They can roll their eye within their sockets, giving the appearance of winking. Plecos are usually skittish and quickly hide whenever they sense danger.

As they age, their foreheads enlarge in a peculiar manner.
