Relevant Information:

Baryancistrus beggini is unique within Hypostominae in having a uniformly dark black to brown base colour with a blue sheen in life, and the first three to five plates of the midventral series strongly bent, forming a distinctive keel above the pectoral fins along each side of the body. It is further distinguished by having a naked abdomen, two to three symmetrical and ordered predorsal plate rows including the nuchal plate, and the last dorsal-fin ray adnate with adipose fin via a posterior membrane that extends beyond the preadipose plate up to half the length of the adipose-fin spine. Adults and juveniles dark gray to black with a turquoise blue sheen on fins and flanks. Blue sheen more intense in some, presumably male, adults. First appeared in the DATZ magazine July 1997 and captioned as L239 Ancistrinae sp. 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. 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. Prefers higher temperatures.
