Can Jurupari Eartheater and Royal Farlowella Catfish Live Together?

Jurupari Eartheater is a generally mild-mannered species (3/10), while Royal Farlowella Catfish is peaceful (1/10). This modest difference means Jurupari Eartheater may occasionally assert dominance over Royal Farlowella Catfish.

Jurupari Eartheater and Royal Farlowella Catfish 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: Royal Farlowella Catfish is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 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 4–10 dGH. Regular testing will ensure conditions stay within this range.

To house Jurupari Eartheater and Royal Farlowella Catfish together, plan for an aquarium of at least 297 litres with a minimum length of 120 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), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Plants - Densely covered. Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Jurupari Eartheater is a plant destroyer, which conflicts with Royal Farlowella Catfish's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Jurupari Eartheater and Royal Farlowella Catfish need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.
