Bristlenose Pleco - Ancistrus Cirrhosus : Complete Fish Profile & Care Guide
Table of contents
IntroductionThe Bristlenose Pleco, (Ancistrus Cirrhosus) is a fascinating and peaceful addition to any aquarium. These hardy and adaptable Catfish are exceptional cleaners and can effortlessly acclimate to various water conditions. Not only are they friendly and peaceful, but they can also protect themselves from more aggressive fish due to their bony exoskeleton and sharp spines. While generally getting along with other fish, Bristlenose Plecos can become aggressive towards one another, especially when males are kept in a small aquarium. In fact, it 's not uncommon to find males with their bristles tangled together! With their small size, Bristlenose Plecos can be kept in an aquarium of 10 gallons or more and prefer well-oxygenated water with a slow to moderate flow. They occasionally dart to the surface to swallow air, which can be a sign of low oxygen levels or the presence of ammonia or nitrite in the water. To ensure clean and highly oxygenated water, an undergravel filter system with a powerhead or airstones can be utilized. Smooth substrate, plants, rocks, large twisted roots, and driftwood can create hiding places for these nocturnal fish to retreat during the day. These decorations also make great shelters for their fry, especially if keeping a breeding pair. Bristlenose Plecos sport unique and irregular colouring, with splotches of different shades on various parts of their body, such as green, brown, or grey with yellow or white spots. These catfish grow tentacle-like growths from their head, bony plates, and have a broad head with an underbite to the lower jaw set, which makes them excellent suckerfish.

BreedingBreeding Bristlenose Plecos is a straightforward process that can easily be achieved in a typical tank environment. However, adding driftwood or caves to the tank can encourage mating behaviour among the plecos. Once the males have matured, they will stake out a specific area for spawning. During mating season, females will lay their eggs in the male 's territory. To induce spawning, a 75% water change is recommended, as water transformations during the Amazon 's rainy season can spur mating behaviours in the wild. Male plecos will fiercely guard their territory, often resulting in fights with other males that may cause their bristles to become tangled. Once ready to breed, the female will attach her eggs to hard surfaces such as cave tops, driftwood, or other suitable tank decorations. For 5-10 days, the male will defend the spawning area until the eggs hatch. After hatching, the fry will absorb their egg yolk for a few days before moving on to algae as their primary food source.
Diet & feedingThe Bristlenose Plecos are primarily herbivorous and rely on algae and other detritus as their main source of nutrition. Thus, a diet primarily composed of spirulina or algae wafers is optimal for their health and well-being. Supplementing their diet with high-quality flakes, granules, and bloodworms is an excellent way to provide balanced nutrition. Treating them to blanched vegetables occasionally can also be appreciated and beneficial for their diet. Overall, a varied and nutritious diet is key to ensuring the optimal health of the Bristlenose Plecos.
