Baryancistrus demantoides • Loricariidae • Cat-eLog

Cat-eLog Data Sheet
Scientific Name	**Baryancistrus demantoides** Werneke, Sabaj, Lujan & Armbruster, 2005
Common Name(s)	L200, Green Phantom Pleco
Type Locality	Río Orinoco drainage, Río Ventuari near ornamental fish market, in river, 04.07565°, -066.89285°, Venezuela, Amazonas,
Pronunciation	bah ree ann siss truss - dee man toy dees
Etymology	Greek, barys = heavy + Greek, agkistron = hook - Essentially "Heavy Ancistrus". The specific name refers to a demantoid, a type of garnet that ranges in color from yellowish green to brownish green and it is in reference to the color of the fish. The word comes from the obsolete German word diemant meaning diamond and the Greek suffix -oïdes meaning to resemble
Species Information
Size	150mm (5.9") SL. Find near, nearer or same sized spp.
Identification	The colouration of this fish can only really be confused with Hemiancistrus subviridis. The key to tell these two apart is that the dorsal fin and the adipose fin are connected in this species, and separated in the Hemiancistrus species. On a more technical side, this is the keys to distinquish the fish from original species description: Baryancistrus demantoides can be distinguished from all other Loricariids except Baryancistrus niveatus, Parancistrus, and Spectracanthicus by having the dorsal and adipose fins connected by an expanded posterior section of the dorsal-fin membrane. Baryancistrus demantoides can be separated from the other species with connected dorsal fins by having a yellow-olive color with white or cream colored spots (vs. typically dark with white, gold, or no spots); from other Baryancistrus with the dorsal fins connected by having the spots only on the anterior portion on the body (vs. all over), from Parancistrus by not being dorsoventrally flattened, and from Spectracanthicus by having greater than 30 teeth per jaw ramus (vs. less than 25). There is one other described species of Baryancistrus (B. longipinnis) that has an expanded posterior membrane of the dorsal fin, but the membrane does not connect to the adipose fin as in B. demantoides and B. longipinnis lacks light spots.
Sexing	Mature males have broader head and more notable odontodes at the cheek and pectoral fins.
Habitat Information
Distribution	Río Orinoco at its confluence with the río Ventuari and the lower río Ventuari upstream into the río Guapuchi. Orinoco (click on these areas to find other species found there) Orinoco, Upper Orinoco, Ventuari (click on these areas to find other species found there) Orinoco, Upper Orinoco, Ventuari, Guapuchi (click on these areas to find other species found there) (Click the map-icon to show/hide map of species distribution)
pH	6.0 - 7.8
Temperature	24.0-27.0°C or 75.2-80.6°F (Show others within this range)
Husbandry Information
Feeding	Should be fed a mainly vegetarian diet, with plenty of fibre in the diet. Algae wafers as well as fresh vegetables such as courgette (zucchini) and tubers such as potato and sweet potato are good foods.
Furniture	In nature they are found on granite rocks, so a tank decorated with smooth rocks would be suitable.
Compatibility	Peaceful, but can be mildly territorial.
Suggested Tankmates	Suitable with most small to medium sized peaceful fish.
Breeding	Unreported.
