Tatia

Tatia is a genus of freshwater catfishes native to tropical South America. The exact family placement of Tatia has varied among authorities, reflecting ongoing revisions in Neotropical catfish systematics; it has been associated with Doradidae (thorny catfishes) in some classifications and with other related families in others.

Species in this genus are typically small to medium-sized bottom-dwellers with the characteristic features of catfishes, including barbels and a generally elongated body. They inhabit slow-moving rivers, streams, and floodplain habitats where they can shelter among submerged structures. Tatia species are usually nocturnal and feed on a mix of benthic invertebrates, detritus, and small organisms available near the substrate.

Distribution covers tropical freshwater systems in South America, with many species occurring in the Amazon basin and surrounding river networks, as well as other northern and central South American basins. Habitat preferences often include soft substrates and vegetated or structurally complex areas that provide cover.

Reproduction and behavior are species-specific, and information is variable across sources. In the wild, Tatia fishes may exhibit diverse reproductive strategies, and breeding behavior observed in captivity tends to be highly dependent on the particular species and environmental conditions.

In the aquarium hobby, some Tatia species are kept for their peaceful disposition and modest size. They typically require stable water conditions, appropriate hiding places, and care tailored to the needs of the particular species; outcomes can differ substantially among members of the genus.

Conservation status varies by species, with many data-deficient due to limited research on small, range-restricted catfishes. Habitat degradation and pollution pose potential threats to several Tatia populations.
