Plecostomuses are omnivorous but, in the wild, feed mostly on plant material at night. During the day, their unusual omega irises block a lot of the light out of their eyes. The iris opens at night. Plecos can also wink by rolling the eye into the head.

Plecostomus, pleco, or plec is a general name for a type of freshwater tropical Central and South American fish belonging to the family Loricariidae. Plecos are extremely popular in aquaria for their ability to clean tanks by eating algae growth. These fish are typically sold at about 8 cm (3 inches) and may grow up to 60 cm (2 feet), and a few species can reach even more. A relatively new species is hardy and grows to a maximum of 10 cm (4 inches), an ideal size for small to average size tanks.
