[Ebook] 500 freshwater aquarium fish – Catfish – Spotted Bristlenose (Ancistrus dolichopterus)
There are around 50 described species of Ancistrus and an almost equal number of undescribed ones referred to by their “L” number, which is their “Loricariid number,” e.g. Ancistrus sp. Orange Spot (LI 10). For detailed information on this genus, it is therefore advisable to consult specialist literature. In all species, mature males exhibit the characteristic filament-like outgrowths of the snout—the “bristlenose”—from which one of its common names is derived.
