Spotted Danio

The Spotted Danio, also known as the Dwarf Spotted Danio, is one of the smallest danio species available in the aquarium trade. Native to Myanmar, these tiny fish feature a beautiful pattern of dark spots along their flanks on a golden-yellow to silvery background. Their small size and peaceful nature make them perfect for nano tanks and small community aquariums. Unlike their larger cousins like zebra danios, Spotted Danios have a more refined, delicate appearance and are less boisterous. They are active swimmers but their small size means they won't dominate a tank or intimidate other small species. They are excellent for planted tanks where their spotted pattern and constant movement create visual interest. Their hardiness and ease of care make them an ideal choice for beginners looking to stock smaller aquariums with active, colorful fish.

Care Requirements

Tank Setup

Spotted Danios are perfect for nano and small community tanks of 10-15 gallons. They appreciate a well-planted aquarium with open swimming areas. Use gentle filtration to avoid strong currents that might stress these small fish. Dark substrate helps their spotted pattern stand out. Provide hiding spots with plants and decorations.

Water Quality

• Temperature: 72-79°F (22-26°C)
• pH: 6.5-7.5
• Water Hardness: Soft to moderate, 2-15 dGH
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm

Feeding

These omnivores accept small flake foods, micro pellets, and frozen or live foods. Due to their small size, crush flakes or use fine pellet sizes. They eagerly take brine shrimp, daphnia, and other small live foods. Feed small amounts 2-3 times daily to accommodate their fast metabolisms.

Behavior & Compatibility

Spotted Danios are peaceful, schooling fish that should be kept in groups of 6-8 or more. They are suitable for small community tanks with other tiny peaceful species like chili rasboras or small tetras. Their diminutive size means they should not be housed with large or aggressive tank mates. They are active throughout the water column.

Tips for Success

• Keep in larger groups of 8+ for best schooling behavior
• Their small size makes them vulnerable to larger tank mates; choose companions carefully
• Gentle filtration is important; use sponge filters or cover intakes
• They appreciate plants for security but need open swimming space
• Regular small water changes help maintain stable water parameters
• Their spotted pattern becomes more defined in well-maintained tanks with good nutrition
