The most ubiquitous, frequently
occurring and abundant species of this genus. Habitat:
Occurs in all kinds of streams where the substrate
is rocky and the water is flowing. Found in great
numbers in zones of plunging waters. May be found
together with Lithoxus in little forest creeks
as well as in rapids. Description:
The Guyanancistrus generaare
small with a flattened body and a large suckermouth.
Similar to the Ancistrus genera but the edge
of the snout is ossified and free of tentacles with
short, bristle-like odontodes. Distinguished from
the Pseudancistrus genus by the absence of
much prolonged odontodes on the edge of the snout
in sexually mature adults. Aquarium Care:
Not the easiest genera to keep as they will need clean,
oxygen rich water and a strong current. Peaceful species.
Diet: Mainly vegetable foods such
as lettuce, spinach, cucumber, zucchini and the addition
of vegetable tablets and pleco wavers. Remarks:
A very variable species (group) that may actually
consist of several closely related species with G.
brevispinis restricted to Nickerie River, its
type locality.
South America:
Atlantic coastal drainages of the Guianas, from Nickerie
to Oyapock River basins. Type Locality:
Fallawatra R., rapid 5 km southwest of Stondansie
Fall, Nickerie dist., Suriname.
Size:
14.0cm. (5½ins)
