Emerald Dwarf Rasboras are tiny little fish with lots of spunk! They usually feature a beautiful coral pink or sun-kissed orange coloration, but what really makes them stand out is the striking turquoise green stripes along their sides that glow brilliantly under any lighting (these stripes may appear more purple in color on some fish). They also have a dark spot at the base of their caudal fin. Males tend to be a bit smaller than the females and have red or orange fins, while females have clear fins and are a bit less colorful than their male counterparts. Their diminutive size makes them perfect for nano tanks!
Emerald Dwarf Rasboras are fairly easy to care for, as long as they live in stable water parameters with good water quality. These fish are peaceful and thrive in groups; however, they are shoaling fish rather than a schooling fish, so the males will often dance and spar with each other. The more of these fish there are in your tank, the less shy they will act. When these fish are healthy and are placed in a well-cycled and densely planted aquarium, it is fairly likely that they will spawn, and you may see fry start to appear. Like all rasboras and danios, they are very peaceful and totally safe to keep with other fish (as long as the other fish are peaceful, too!), snails, shrimp, and live plants. They do best in tanks that have plants, rock, or driftwood that provides them with cover.
Emerald Dwarf Rasboras may eat fish flakes or pellets, but they are known to prefer live foods such as brine shrimp, microworms, daphnia, and insect larvae. They may also accept prepared foods such as frozen brine shrimp and bloodworms. Our Emerald Dwarf Rasboras are tank-raised, and we ship out as juveniles or young adults that are about a half inch in length, and they may grow up to ¾ of an inch. These fish are also sold under the names Emerald Dwarf Danios, Thick band Purple Zebra Danios, and Cross-banded Dwarf Rasboras.
