Exclamation Point Rasbora

Exclamation Point Rasbora (Boraras urophthalmoides)

The Exclamation Point Rasbora is a tiny but captivating nano fish that packs an incredible amount of personality and beauty into a remarkably small package. Named for the distinctive dark marking near its tail that resembles an exclamation point, this peaceful species is a favorite among aquascapers and nano aquarium enthusiasts. Its translucent body, subtle golden hues, and active schooling behavior create a natural and elegant display in planted aquariums.

Native to the slow-moving waters of Southeast Asia, Exclamation Point Rasboras thrive in heavily planted aquariums with gentle filtration, dark substrates, and plenty of cover. Their small size allows them to navigate dense vegetation with ease, while their constant activity adds life and movement throughout the aquarium. When kept in large groups, they display more natural behavior and create a mesmerizing schooling effect.

These peaceful fish are ideal for nano community aquariums and coexist well with shrimp, small Corydoras, other micro rasboras, and similarly sized tank mates. They readily accept finely crushed flakes, micro pellets, baby brine shrimp, and other appropriately sized foods. A varied diet and stable water conditions help bring out their best coloration and overall health.
