Blue Longfin Danio

The Longfin Blue Danio is a type of Zebra Danio, or danio rerio, bred in India to display more of the blue gene in the aquarium. This community schooling fish has a lined and spotted blue body and does well in groups of six or more. These aquarium fish are hardy and great for beginners or for advanced aquarists with planted fish tanks.

Quick Facts

Care Guide

Tank setup: Danios are fast swimmers, so give them open swimming space, a filter, plants around the edges and a tight-fitting lid, since they jump. Make sure the tank is fully cycled (which takes several weeks) before adding fish.

Feeding: Feed a quality flake or small pellet once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen foods like bloodworms and brine shrimp.

Tankmates: Danios get along with most peaceful community fish, such as tetras, rasboras, barbs, corydoras and livebearers. Their speed can stress slow, long-finned fish like bettas and fancy guppies, and large predatory fish will eat them.

Good to know: Long fins make these danios a little slower than regular zebras, so avoid fin-nipping tankmates like tiger barbs.
