Black Harlequin Rasbora

The Black Harlequin Rasbora, Rasbora heteromorpha, is very stunning nano fish. Reaching a max size of about 1 inch, these fish are a great addition to any community tank. They have an amazing coloration of orange while having a pork chop shaped dark patch toward their tail. 

Please Note: All fish shipments have a 100% Live Arrival Guarantee when shipping with FedEx Overnight (1 Day) option. All other options void our Live Arrival Guarantee for fish. 

Like most nano fish, the Harlequin Rasbora does best in groups of 10. They prefer to have open space to switch in the aquarium. In nature they come from soft acidic water. Leaves, driftwood and cones come in handy to reproduce their natural habitat. They are very hardy and accept a wide range of parameters. 

We feed these guys a mix of frozen daphnia, baby brine and cyclops.

Absolutely Beautiful

Fish were healthy and active and colored up quickly. Probably the best bagged and shipping I've seen when it comes to fish.

Beautiful little fish!

All of the fish arrived alive (including one extra), and looked super alert and healthy. They were packaged well, and in the box were detailed instruction on how to acclimate them. Since then they have become so active and have colored up nicely. They are gorgeous, entertaining little guys, and I love watching them in my tank. Would definitely buy more!
