Baryancistrus xanthellus is distinguished from
all other Baryancistrus species by the presence
of yellow spots along the entire body and conspicuous
yellow marks on distal tip of dorsal and caudal fins.
Habitat: This species has been recorded
from the area called Volta Grande do rio Xingu, an
area immediately above Belo Monte falls, and from
Rio Iriri, the larger tributary of Rio Xingu. Pictures
of L085 are adult specimens of L018. The same species
are L177, LDA060 and also L081 and they all have different
colourations and patterns. Description:
They are large and high backed. They have a large
sucker mouth 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. Found
in shallow fast flowing areas of water with a stony
substrate. 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. Adults
can prove to be extremely territorial. Sexual
Differences: Mature males have a broader
and longer head and longer pectoral fin spines. Diet:
Vegetarian diet, and will also eat plants in the aquarium.
