Merah Rasbora

The Merah Rasbora is an amazing fish with a great temperament. They are very timid so this makes them a great addition to a shrimp or snail tank. The Merah Rasbora can reach lengths of just under 1 inch. Their scientific name is Boraras merah. 

Please Note: All fish shipments have a 100% Live Arrival Guarantee when shipping with 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 slow moving black water streams. They prefer lots of leaves, wood and rock work. Therefore, these fish are the perfect addition to a well planted buffered aquarium (PH less than 7). In nature, the Merah Rasbora feed on micro organism and small insects.

Merah Rasbora

After a week, my Merah Rasbora school is healthy, active and adorably cute. I wanted some small fish that would live well with shrimp and these guys are perfect! I'm so glad I picked them.
