Acestridium is a genus of freshwater fish in the family Loricariidae of order Siluriformes. The type species is Acestridium discus. The genus name is derived from Latinised Greek 'agkistron' meaning hook.[1]

Acestridium species are native to small streams of the Amazon region of Brazil, Venezuela, and Colombia.[2] Species of this genus are found in litter banks.[3]

Members of this genus typically are long and thin, or 'twiglike' and superficially resemble the genus Farlowella of the same family. Adult length is 5-7 cm and each species shows adaptation for camouflage in the water margins - bright green leaf like in Acestridium dichromum[4] and varigated brown in other species.[5]
