Hypostomus robinii,[1] commonly known as the teta, is a species of catfish in the family Loricariidae. It is native to the Caribbean, where it occurs in freshwater habitats on the island of Trinidad. It inhabits fast-flowing streams, where it feeds on periphyton.

The species reaches 16 cm (6.3 inches) in standard length.[2] It can reach a weight of almost 350 grams. This species, known in the vernacular as the "armored catfish" because of the bony plates on its body, is quite popular in the aquarium trade.[3] Because of this, there have been several documented cases where the fish has been released into wild river systems.[4][5] Female Hypostomus robinii can release upwards of 200 eggs during spawning, and as a result, the fish can rapidly take over water systems in short time periods. Researchers have developed a method to monitor this invasive aquatic species using environmental DNA samples.[3]
