Sailfin Armoured Catfish (Pterygoplichthys sp.)
Lower Seletar Reservoir, 30th June 2016

Several species of Sailfin Catfishes (Pterygoplichthys spp.) have been introduced to various parts of the world, probably due to the release and abandonment of aquarium pets.

Three similar-looking species of Sailfin Armoured Catfish are believed to have feral populations in Singapore:

Amazon Sailfin Catfish (Pterygoplichthys pardalis)

Vermiculated Sailfin Catfish (Pterygoplichthys disjunctivus)

Spotted Sailfin Catfish (Pterygoplichthys joselimaianus)
