Black Banded Rainbow 5cm

Black Banded Rainbow

Rainbowfish are often known for their vibrancy and striking colours which is why they are often a must-have fish for community or planted display aquariums. There is usually an abundance of blues, reds, oranges, and more which would seem somewhat out of place when trying to go for a more natural-themed aquarium however this is where the Black-banded banded rainbow fish comes in. A truly underrated species and a perfect contender for biotope-type aquariums the black banded rainbowfish is a perfect example of stunning simplicity. 

The black-banded rainbowfish as the name suggests has a striking jet-black band running from head to tail. The top half of their body colour has varying shades of an olive-green colour with highlights near the face and fins. The bottom half is a simple cream or white colour which just creates the perfect natural blend of colours on this fish. Surprisingly the black banded rainbowfish looks amazing in almost any aquarium setting because its simplicity contrasts really well with other flashy tank mates. Black-banded rainbows are a great species for smaller aquariums, they only reach a maximum of 10 cm. 

Black-banded rainbowfish can be bred in the home aquarium quite commonly as once they reach maturity, females lay eggs on an almost daily basis. Aquarists often make spawning mops out of acrylic yarn and place these into the aquarium, the females will swim through the yard and lay a few eggs which the male will then fertilize. The eggs can then be collected and raised in a separate aquarium which makes for a great hands-on experience. Males tend to have larger fins and a slightly deeper body compared to the smaller shape of females. 

Tank Recommendations for your Black Banded Rainbow

Black-banded rainbows on average do reach around 10 cm but can get slightly larger than this as well. They are an incredibly active species. It is best to keep them in the tank with a minimum volume of 70 liters. A trio of these fish can be kept in here comfortably. They will be totally safe in a planted aquarium and will not only love the natural cover but also look great. They are mostly mid to top water-dwelling fish so the choice of substrate and aquarium hardscape is not a major concern. Rainbowfish, in general, are however excellent jumpers so a tight-fitting lid is a must for the aquarium. These are also tropical fish that are best kept at 24-26 degrees.

Suitable Tank Buddies

The black-banded rainbowfish is incredibly peaceful but due to their speed, they may potentially outcompete slow or bottom-dwelling tank mates. They can however be kept in a wide range of community aquarium settings and with other rainbow fish strains.
