The Royal Farlowella (Sturisoma panamense), also known as the Twig or Whiptail Catfish, is a member of the Loricariidae family of South American suckermouth catfishes. While many suckermouth catfish species have yet to be bred on any major scale in aquariums, the Royal Farlowella has been bred by a few farms. This fish is highly unique with its very thin, twig-like appearance and the “streamer” extensions on its tail.
