Can Red Striped Eartheater and Rummynose Rasbora Live Together?
Keeping Red Striped Eartheater and Rummynose Rasbora together is possible but requires caution, though some care is needed. Provide a spacious tank of at least 261 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Can your tank handle Red Striped Eartheater and Rummynose Rasbora?
Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.
Behaviour & Temperament
Red Striped Eartheater is a generally mild-mannered species (4/10), while Rummynose Rasbora is peaceful (2/10). This modest difference means Red Striped Eartheater may occasionally assert dominance over Rummynose Rasbora.
Red Striped Eartheater and Rummynose Rasbora both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Water Parameters
The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.
Both fish can tolerate a pH between 7.3 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 10–10 dGH. Regular testing will ensure conditions stay within this range.
Tank Setup
To house Red Striped Eartheater and Rummynose Rasbora together, plan for an aquarium of at least 261 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), Leaf Litter/Blackwater, Plants - Densely covered. Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
Why This Pairing Needs Extra Planning in Practice
This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Red Striped Eartheater and Rummynose Rasbora 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.
