Identity and locality
Ancistrus ranunculus (1994)
Rio Xingu and Tocantins basins, Brazil
Diagnostic evidence and naming
A distinctive broad-headed, flattened, rheophilic bristlenose. Juvenile pale spots generally fade with maturity; visually similar L255 retains spots into adulthood. ZooBank traces the 1994 original species description to the Xingu and Tocantins rivers; the L034 code is an aquarium identifier, not a separate breed.
Breeding and genetics limitations
Cave spawning with male guarding is described in specialist care literature. Requires oxygenated current and careful stock-specific feeding; published parameters are not universally applicable to other Ancistrus.
