Can Gold Nugget Pleco (L018) and Uaru Live Together?

Gold Nugget Pleco (L018) is a moderately assertive species (6/10), while Uaru is generally mild-mannered (4/10). This modest difference means Gold Nugget Pleco (L018) may occasionally assert dominance over Uaru.

Gold Nugget Pleco (L018) and Uaru both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Gold Nugget Pleco (L018) and Uaru to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations.

The safe temperature window for both species falls between 27°C and 30°C. Aim for the midpoint of this range (around 28.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 2–8 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Gold Nugget Pleco (L018) and Uaru together, plan for an aquarium of at least 480 litres with a minimum length of 150 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Sand (Sifters). Meeting these requirements will help both species thrive.

Gold Nugget Pleco (L018) prefers High (River/Stream) flow while Uaru needs Low (Still Water) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
