The plecostomus, more commonly known as the suckermouth catfish, is omnivorous and feeds on algae, blood worms, aquatic plants and small crustaceans such as brine shrimp. In captivity it can be fed a diet of pellets, spirulina flakes or algae wafers.
The sucker shape of its mouth allows it to adhere to surfaces, making it a popular cleaner fish for freshwater aquariums. It feeds at night and is a bottom dweller that scavenges for uneaten food and algae.
The suckermouth catfish is native to Central and South America, particularly Costa Rica, Panama and Uruguay. It has a lifespan of up to 15 years.
