Care notes

A minimum tank size of 60 liters is sufficient for a group of 5-6 dwarf loaches. Temperature should be 24-28°C, pH 6.5-7.5, GH 5-12. Fine sand substrate is preferable to protect their barbels. Provide dense plants, driftwood, and rocks for hiding. Moderate water flow is appreciated. They are omnivorous: micro-pellets, frozen and live foods. Avoid large or aggressive fish. Regular water changes are essential as they are sensitive to nitrates. Breeding in captivity is rare.
