General: The Bristlenose Plecostomus (Ancistrus cirrhosus) are a benthal (bottom oriented) fish species living within the heavily planted regions of the Amazon River. The Bristlenose is well adapted to the nearly anoxic (poorly oxygenated), stained wetland waters. The Bristlenose is primarily herbivorous, as it applies a unique sucker mouth to rasp algal materials off large rocks, and woody debris. The Bristlenose will reach a length of five inches, and can live over five years in captivity.

Fecundity: The Bristlenose (Ancistrus cirrhosus) may produce several hundred eggs per clutch.
