    South America: South American lakes and rivers.

General Body Form:
    Similar to most other plecostumus, Flat stomach with convex back.

    Brown to black body with light to deep yellow spots all over.


    The Gold nugget pleco is an excellent addition to a community aquarium and can be housed with most community fish but Best kept as a single specimen and perhaps even as the only bottom dweller. Territorial with other gold nugget plecos and may show aggression towards other types of pleco. As with all plecos, the gold nugget is a messy fish, it requires a good filtration system. The gold nugget pleco also benefits from fairly strong current and highly oxygenated water. The aquarium should have caves and drift wood. Does not damage live plants. Not suitable for beginner aquarists. A well-established aquarium is best. When choosing your gold nugget pleco insure the tummy area does not appear sucked in.

    Baryancistrus sp., L018


    Gold nugget pleco,  L177

    Baryancistrus sp., L177


    The gold nugget pleco is more carnivorous than some other plecos. Feed algae wafers, veg and meat such as bloodworms.

    Susceptible to bacterial and fungus infections, which frequently occur in the bottom substrate. Regular vacuuming needed.

    Found most frequently in cracks and empty spaces or gaps of granitic rocks in flowing water

    Males have a flatter, more level slope to their foreheads and are slightly wider. Females have a more rounded forehead and are slightly plumper when in spawning condition they are egg layers and require current to flow directly into the cave. The female should be removed after spawning.
