Origin and Distribution

The Bristlenose Pleco originates in South America, mainly found in the fast-flowing waters of the Amazon River Basin. They can also be found in other parts of south and central America including Panama.

The appearance of Bristlenose Pleco

The Bristlenose Pleco is one of the smallest aquarium catfish and grows up to an average of 3 – 5 inches. They have bony plates, a flat, fat body, and a wide head. As they reach maturity, they sprout tentacle-like branches from their head. The tentacles on the male,s head are longer than females. They have a pair of pectoral and abdominal fins, and around the mouth with elongated lips which make them an excellent suckerfish.

They are usually black, brown, olive, or grey with light white or yellow spots all over the body. The underneath side of the fish is lighter in color than the main body (with the exception of the albino Bristlenose Pleco, which is mostly white). They can sit motionless for hours.

Bristlenose Temperament & Tankmates

They spend most of their time at the bottom of the tank or sucking on the side of the aquarium. They are a peaceful species and will get along with most other peaceful fish. They are great fish for beginners and experienced aquarists. They can adapt to live in a wide variety of tank conditions.

Do not put two males together as they get extremely territorial and competitive with other similarly shaped species. They have armor that protects them against semi-aggressive, small aggressive fish. However, you must monitor them if you choose to house them together. Another thing to keep in mind mature Pleco can not get along with fellow Plecos. They can be highly territorial around each other. Therefore, it would be dangerous to hose them together at any age.

Tank Requirments For Bristlnose Pleco

They originate from the streams and rivers in South America. They prefer well-aerated freshwater with some sort of current. Make sure that your tank has is well-oxygenated water with a moderate water flow.

They are nocturnal fish, and you should make plenty of hiding places for them to rest during the day. They like shadowed areas, so the more of these you can create the better. Plants, driftwood, and caves all make an excellent hiding place. Driftwood can provide a good substrate on which algae will consistently grow. This will give a sufficient amount of food for the Bristlenose Plecos.

The water temperature should be kept from 15oC to 27oC, the water hardness should fall within 20-25, and the pH should be within 6.5 to 7.5.

You will need a minimum tank size of 25 gallons, and make sure that the bottom of the tank which is where they spend most of their time, is large.

An under-gravel water system will help to ensure that your tank remains highly oxygenated and will maintain water conditions. Install a filter in your tank. The canister filter is best if you have Bristlenose in your aquarium.

Bristlenose Pleco Diet

They are bottom-feeding fish and have a mostly vegetarian diet. They spend their time hiding out and grazing on the algae that grow on all the surfaces. They eat plenty of algae but algae will not provide them with a blanched diet. Their diet should be consist of around 85% plant matter and 15% protein. You can feed them tablets that have been specifically developed for bottom-dwelling herbivores such as sinking algae pellets or wafers.

Granules, flakes, or bloodworms are also good. Make sure you do not overfeed. Well fed Plecos have good coloration.
