Rummy-nose Tetra Tank Setup and Care
They prefer soft acidic water. Stable temperature is critical. Planted tanks provide comfort. Open space supports schooling.
They thrive in large groups. Ten or more enhances natural movement. Avoid small groups. Consistency prevents stress.
Use gentle filtration. Avoid strong currents. Leaf litter adds tannins. Floating plants diffuse light.
Blackwater setups mimic natural habitat. Include driftwood for structure. Avoid rapid parameter changes. Regular maintenance is essential.
