Dwarf Spotted Danio (Danio nigrofasciatus) 
 
The Dwarf Spotted Danio (Danio nigrofasciatus) is a small yet active freshwater fish, well-loved for its striking pattern of dark spots and bars against a shimmering body. Native to Myanmar, this hardy species is ideal for both beginner and experienced aquarists. Their playful and social nature makes them a fantastic choice for peaceful community tanks.
 
Tank Setup for Dwarf Spotted Danios
A tank of at least 40 liters is recommended for a small school of these danios. They prefer well-planted aquariums with open swimming space, and a gentle water flow mimics their natural stream habitats. Maintain a temperature range of 20°C–26°C and a pH level between 6.0 and 7.5. Regular water changes and a well-maintained filter are essential to keep them healthy and active.
 
Diet and Feeding
Dwarf Spotted Danios are omnivorous and require a varied diet. Offer high-quality flakes or micro-pellets as a staple, supplemented with live or frozen foods like brine shrimp, daphnia, and bloodworms. They also appreciate occasional vegetable-based foods such as spirulina flakes to support their health and coloration.
 
Behaviour and Tank Mates
These danios are peaceful schooling fish that should be kept in groups of at least six. They do well with other small, non-aggressive species like Tetras, Rasboras, Corydoras, and small Gouramis. Avoid housing them with larger or aggressive fish that may intimidate or outcompete them for food.
Breeding Dwarf Spotted Danios
Breeding is relatively straightforward, as they are egg scatterers. A separate breeding tank with fine-leaved plants or a spawning mop can encourage successful spawning. Once eggs are laid, the adults should be removed to prevent them from eating the eggs. Fry hatch within 48 hours and can be fed infusoria or finely crushed flakes until they grow large enough for baby brine shrimp.
