Emerald Dwarf Danio / Dwarf Emerald Rasbora (Danio erythromicron)

Quarantined nano danio for planted and community aquariums in Canada.

The Emerald Dwarf Danio, also commonly sold as the Dwarf Emerald Rasbora, is a tiny patterned nano fish from the Inle Lake region of Myanmar. Its vertical striping, subtle emerald sheen, and small adult size make it a beautiful choice for mature planted aquariums and carefully planned nano communities.

Why This Fish Stands Out

• Tiny patterned nano fish for planted aquariums
• Excellent visual match with Celestial Pearl Danios and other small danionins
• Peaceful schooling behaviour when kept in a proper group

Aquarium Setup & Behaviour

Use a mature planted aquarium with stable water, small foods, gentle-to-moderate flow, and plenty of cover. Avoid large or aggressive tankmates.

Best kept in a group. Emerald Dwarf Danios are more confident, visible, and natural-looking when kept with their own kind.

Feeding

Feed very small foods such as micro-pellets, crushed flakes, frozen cyclops, baby brine shrimp, and other micro foods.

Natural Colour & Livestock Integrity

Colour and pattern come from the fish's natural species traits and healthy conditioning. Topick Aquarium does not use hormones to artificially enhance colour.

Topick Aquarium Livestock Standard

All fish at Topick Aquarium are carefully quarantined and conditioned to our stable local tap water before sale. Danios and killifish can come from very different natural habitats, but stable water, gradual acclimation, species-appropriate feeding, and a mature aquarium are more important than chasing exact wild parameters.

Frequently Asked Questions

Is Emerald Dwarf Danio the same as Dwarf Emerald Rasbora?
Yes. Dwarf Emerald Rasbora is a common trade name, but Danio erythromicron is the current scientific placement used here.

Can it live with Celestial Pearl Danios?
They are often kept in similar planted nano setups, but they should still be provided with a group, cover, and stable water.

Is this fish good for shrimp tanks?
It is generally suitable with adult shrimp, but very tiny baby shrimp may still be eaten.
