Habitat
The Amazon River in South America is the ancestral home of the Ancistrus. It can be found in swamps and lakes in forests, but it prefers the swift-moving rivers and mountain streams.
Because of its hardy nature and distinctive appearance, Ancistrus (Ancistrus dolichopterus), also referred to as the bristlenose pleco, is a popular freshwater fish in the aquarium hobby. This species is prized for its unique bristle-like structures on the males’ heads and its tendency to eat algae, which keeps the tank clean. By being aware of their unique care requirements, including food, tank conditions, and mating habits, one can guarantee a robust aquarium ecosystem and a lively, healthy fish.
Description
The Ancistrus has a long, drop-shaped, flattened body covered in bony plates, and a broad head. The Ancistrus’s mouth resembles a sucker and has strange scrapers that resemble horns that it uses to remove plaque from driftwood, leaves, and the aquarium’s walls.
In certain individuals, the large, flag-shaped dorsal fin is pushed against the back. The pectoral and ventral fins are large and broad, while the adipose fin is small.
The entire body has light patches, ranging in color from a yellowish-gray to dark gray and even black. There is a little less weight in the abdomen. Young individuals can be identified by their dorsal and anal fins’ white edging and body’s bluish tint.
Tentacles are leathery protuberances on the head that identify males from females; in females, these growths are absent or hardly noticeable. Males can grow up to 13 cm and are larger and slimmer.
Aquarium arrangement and maintenance
Ancistrus simple is a very modest fish that can be kept in any kind of freshwater aquarium as long as it has at least 50 liters of capacity. The presence of many caves, snags, and stones—which provide the fish with cover and a place to rest—is a prerequisite for preservation.
In essence, the male selects a favorite cave and remains in close proximity to it, keeping other fish away. Big stones should be firm and rest on the ground to prevent ancistrus from crawling under them and crushing them.
For safety reasons, the filter’s outlet tubes should be closed because ancistrus, which adore strong currents, can swim too near to them, enter the filter, and perish.
Ancistrus can withstand temperature changes of between 17 and 30 °C with ease, although 22 to 25 °C will be the most comfortable. pH: 6.5–7.5; dGH: approximately 15°.
Since the common ancistrus prefers swiftly flowing, oxygen-rich water in the wild, the aquarium must have strong filtration and aeration. Regular partial water changes ought to occur.
Although ancistrus dislikes bright light, it is imperative to provide an intermediate twilight lighting cycle with light and dark phases in order to support plant growth.
The common ancistrus is a very calm fish that gets along well with any other fish that requires similar upkeep.
Nutrition
The common ancistrus prefers to eat plaque that forms on snags, stones, and glass in both the natural world and aquarium environments. This is especially true if the aquarium is well-lit.
Moreover, it consumes live food and plant remnants that other fish avoid. It transitions to plant leaves, particularly young ones, and leaves holes on them if there isn’t any algae growth.
Feed the ancistrus plant foods such as boiling water-scalded cabbage, lettuce, and nettle leaves to prevent damage to the plants.
