Can Banjo Catfish and Contradens Pleco (Snowball Variant) Live Together?

Banjo Catfish is a peaceful species (1/10), while Contradens Pleco (Snowball Variant) is generally mild-mannered (3/10). This modest difference means Contradens Pleco (Snowball Variant) may occasionally assert dominance over Banjo Catfish.

Banjo Catfish and Contradens Pleco (Snowball Variant) 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.

Worth noting: Banjo Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–15 dGH. Regular testing will ensure conditions stay within this range.

To house Banjo Catfish and Contradens Pleco (Snowball Variant) together, plan for an aquarium of at least 120 litres with a minimum length of 80 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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: Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Banjo Catfish prefers Low (Still Water) flow while Contradens Pleco (Snowball Variant) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.
