Please Note: All fish shipments have a 100% Live Arrival Guarantee when shipping with FedEx Overnight (1 Day) option. All other options void our Live Arrival Guarantee for fish. 

We recommend keeping these fish in group of 10 or more due to their timid nature. 

In nature, these fish come from the margins of mountainous lakes where vegetation grows thick. Therefore, these fish are the perfect addition to a well planted aquarium. They prefer more alkaline water and will not do well in acidic setups. In nature, the Dwarf Emerald Rasbora feed on micro organisms and small insects.

Arrived warm, but fish are doing well now. Very colorful and active. I have bloody Mary shrimp and snails in there also.

Dwarf Emerald Rasbora and Amano Shrimp

Received order as advertised... Shrimp and Fish came in breathable bag and seemed none the worse for wear shipping overnight to the east coast. As for the shrimp, my tank is heavily planted with plenty of cover, and I occasionally one. I assume all five are in good condition. The Rasboras are doing well in my 75 gal with tiger barbs, tetras, algea eaters, and clown loaches.
