Pterygoplichthys anisitsi also known as the Paraná sailfin catfish, southern sailfin catfish, is a species of catfish in the family Loricariidae. Its natural range is the middle Paraná and Uruguay River basins of south-central South America, but it has been introduced to North America and South Asia, probably via the pet trade. Like other loricariid catfishes, Pterygoplichthys anisitsi has a ventral mouth modified into a sucking disk and a body covered in bony plates. The species typically has a dark and white spotted body pattern, although some individuals are very dark with few spots. It reaches 55 cm in total length and can weigh up to at least 2.3 kg.
Ancistrus ranunculus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the basins of the Xingu River, Trombetas River and the Tocantins River in Brazil. It inhabits areas with clear water and without strong currents, and it is known to inhabit narrow cracks in submerged rocks, small passages, and spaces below flat rocks. The species is large for a member of Ancistrus, reaching 19.5 cm (7.7 in) in total length. It sometimes appears in the aquarium trade, where it is one of several species known as a medusa pleco, although it may be referred to by its L-number, L034.

The species reaches 24 cm in total length. Its specific epithet, ericae, honors Erica Pellegrini Caramaschi, who collected the first specimens of the species. The fish was formally described as a species new to science in 2005 by Pedro Hollanda Carvalho and Claude Weber in 2005. Characteristics that distinguish it from other catfish in genus Hypostomus include the number of odontodes in the opercle; its colour pattern, which features widely spaced spots on its body; the presence of a buccal papilla; and the depth of its caudal peduncle.
