Long Fin Zebra Danio

Long Fin Zebra Danios, Brachydanio rerio, are one of those fish that bring instant movement to a freshwater aquarium. They are small, hardy, active, and seriously fun to watch as they zip around the tank in a group!

These fish have the classic blue and silver striping that Zebra Danios are known for, but with longer, flowing fins that trail behind them as they swim. They stay around 2 inches, making them a great option for peaceful community tanks, planted aquariums, and beginner friendly setups.

Long Fin Zebra Danios are very hardy and adapt well to a range of water conditions, which is one of the reasons they are such a popular fish for new hobbyists. They are peaceful, but they are also VERY active, so they do best with tank mates that don’t mind a little extra energy in the tank.

Like most schooling fish, Brachydanio Rerio should be kept in groups of 6 or more. A larger group helps them feel more secure and also brings out their natural schooling behavior. Give them open swimming space, some plants, and a peaceful community, and they’ll be all over the tank doing their little danio thing.
