Harlequin Rasbora

To protect our animals and to ensure they get to our customers healthy, we will only ship orders with Nano Fish via UPS Next Day Air.

Harlequin Rasboras are beautiful Nano Fish and are one of the more popular Rasbora species in the hobby. They have a beautiful bronze, metallic color with a unique pattern on their bodies. They are a smaller fish and can grow to a a max size at about 1.25 inch. 

Like most Rasboras, we recommend keeping these guys in groups of 5 or more for them to feel safe in a large school. They are a naturally schooling fish so having a large school of these guys is pretty cool to watch! They will look especially stunning in a planted tank.

These fish should not eat adult shrimp but might go after small shrimplets, we recommend having sufficient plants or hiding spots for aquariums with both Harlequin Rasboras and freshwater shrimp. 

These Nano fish are naturally found in soft, acidic water in their natural habitat. However, they are pretty easy to care for and can acclimate to a wide range of parameters.  The following are our water parameters we keep them at:
