Baryancistrus sp. (L047)



    Baryancistrus is one of the rarer to find plecs but can be obtained with a bit of research. This plec is very distinctive with it’s olive green body and yellow tipped dorsal and caudal fins. It makes a great and unusual addition to a tank for those that lack the facilities to house the bigger species. The Magnum can grow up to 11″ and is always supplied wild caught which makes for stunning colouration. It can be expensive, but is an addition most will love.

Quick stats:

Listed tank sizes are the minimum
Size: 9 – 11 inches (22.9 – 27.9cm)
Tank: Juveniles and Sub adults (up to 18 months) can be kept in a 30-40G tank but adults must have a minimum of 60G tank.
Strata: Will go everywhere but predominantly bottom. Likes Sand – Medium Gravel.
PH: 6.5 – 7.5
Hardness: dh range 8 – 12dH
Temperature: 72°F to 80°F (22°-27° C)


Order: Siluriformes
Family: Loricariidae
Genera: Baryancistrus

Common name:


Magnum Pleco

    , Mango Pleco.


    South America: Rio Xingu, Brazil.

General Body Form:

    Similar to other plecostumus but young tend to be stocky in appearance.


    Baryancistrus sp. (L047) is an olive green with stunning yellow tips on the dorsal and caudal fins.


    This plec is a great addition to the standard community tank. It does require highly oxygenated water and the lack of this can be seen easily by a reddening around the mouth (this usually returns to normal fairly quickly with the addition of more surface agitation). As with most plecs a good filtration system is a must as lots of waste will be produced as the plec grows. Heavily planted tanks and natural caves with driftwood are preferred.

    As with most other plecs this species is happy with Algae wafers but really loves a variety of fresh fruit and vegetables. This species is not fussy about it’s food, but care must be taken with the young. This is always a wild caught plec and must be monitored closely for evidence of feeding as it can take sometime to adjust to a captive life, and neglected magnums can suffer very quickly. For the young try soft vegetables such as cucumber first.


    An Easy to care for plec, but as with any wild caught plec (fish) initial care must be taken.


    Amazonian river basin, slow – medium currents but quite happy with fast surface water.


    Not known to have been bred in captivity.
