L047 has finely been described by Py-Daniel et al 2011 as Baryancistrus chrysolomus. Colouration: This species can be distinguished from all its congeners, except B. xanthellus, by the presence of a broad orange to yellow band along the entire distal border of dorsal and caudal fin (vs. all fins without yellow bands). Description: This genus is large and high backed. They have a large suckermouth with a high number of slender and long stemmed teeth. A small membrane lies behind the last ray of the dorsal fin which joins the anal fin. Habitat: Found in shallow fast flowing areas of water with a stony substrate. Adults occur under large flat rocks settled directly on the river bottom, in places with considerable amounts of fine sediments. Young individuals inhabit marginal areas of the rapids, near the river banks, usually just one or two individuals. They occupy under rocks in places with slow to moderate flowing waters, usually with sediment accumulation over the rocks and river bottom. Aquarium Care: Can be problematic, especially with inexperienced aquarists, not a beginners fish. As of most of this genera the adults can be extremely territorial, especially with their own kind and other species of Baryancistrus. Prefers higher temperatures. Sexual Differences: Mature males have a broader and longer head and longer pectoral fin spines. Diet: Based on two specimens, this species feeds mainly on diatoms and occasionally on invertebrate larvae associated with fine sediments and sand grains. In the aquarium provide a vegetarian diet such as cucumber and courgette and also other foods offered such as frozen bloodworm, insect larvae and prawns/shrimp foods. Etymology: The specific name chrysolomus: From the Greek chryso, meaning orange or yellow and loma meaning border, in allusion to the coloured band at the border of the dorsal and caudal fins. A noun in apposition.
