The Emerald Dwarf Danio (Danio erythromicron) is a truly captivating nano fish, perfect for heavily planted aquariums. Originating from Myanmar, these tiny, iridescent beauties boast a striking metallic green-blue body adorned with delicate vertical bars, which shimmer under appropriate lighting. Growing to a mere 1 inch (2.5 cm), they are a peaceful and somewhat shy species, best kept in groups of at least 6-10 individuals to encourage their natural shoaling behavior and reduce stress. Their small size makes them ideal for desktop nano tanks (5+ gallons recommended) or as a delightful addition to larger community aquariums with other small, non-aggressive species. They thrive in well-established tanks with stable water parameters, preferring soft to moderately hard water and a slightly acidic to neutral pH. Providing ample live plants, especially fine-leaved species and floating plants, will offer them security and enhance their vibrant coloration. Their diet should consist of high-quality micro pellets, crushed flake food, and small live or frozen foods like daphnia, cyclops, and baby brine shrimp. Observing a healthy shoal of Emerald Dwarf Danios darting through lush foliage is a truly rewarding experience for any aquarist.
