Compatibility - can they live together?

Mixing Monte Carlo and Dwarf Baby Tears in one tank depends on adult size overlap, territory needs, and water-chemistry match. Peaceful/Peaceful pairing means both species share similar temperament so direct fights are rare, but resource competition (food, territory, hiding spots) is common. Both species need water parameters within 74-80°F and 74-80°F. If keeping together, introduce the more peaceful species first by 2-4 weeks, provide multiple hiding spots, and feed at separate ends of the tank.
