Exclamation Point / Least Rasbora (Boraras urophthalmoides) – Group of 10 Fish


A unique and actively schooling “micro” Rasbora found throughout Southern Thailand, the Exclamation Point or Least Rasbora Rasbora makes an ideal addition to a nano aquarium or planted tank. In the wild, they inhabit slow moving streams and creeks with sandy substrate and soft, acidic and often tannin-stained waters, usually among aquatic plants or fallen branches. A hardy and adaptable fish in the aquarium, they are popular with aquascapers due to their small adult size, active nature, and distinctive markings. Like most schooling rasboras, they are best kept in groups of 10 or more and will thrive with most similarly-sized peaceful tankmates.
