Exclamation Point Rasbora

The Exclamation Point Rasbora is yet another fun fish from the Boraras genus. These small fish are perfect for nano aquariums and can be kept with shrimp. They prefer schools of 10 or more although males can get a bit territorial during breeding. We’d recommend keeping these in a 10-gallon tank or larger.

The Exclamation Point Rasbora reaches a max size of just under 1 inch. They are the smallest fish of their genus found in the hobby. They originate from slow-moving to stagnant water. Therefore, they do not need intense filtration or water movement.

The scientific name for the Exclamation Point Rasbora is Boraras urophthalmoides.

We feed our Exclamation Point Rasboras a mix of baby brine and Northfin Fry food. We also supplement their diet with a blend of North fin Veggie and Community.
