Can Jurupari Eartheater and Tequila Splitfin Live Together?

Jurupari Eartheater is a generally mild-mannered species (3/10), while Tequila Splitfin is moderately assertive (5/10). This modest difference means Tequila Splitfin may occasionally assert dominance over Jurupari Eartheater.

Jurupari Eartheater and Tequila Splitfin 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

There is no temperature overlap between Jurupari Eartheater (26–30°C) and Tequila Splitfin (20–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7 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 6–10 dGH. Regular testing will ensure conditions stay within this range.

To house Jurupari Eartheater and Tequila Splitfin together, plan for an aquarium of at least 280 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.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Sand (Sifters), Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), 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 Tequila Splitfin'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.

Jurupari Eartheater and Tequila Splitfin are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.
