Dwarf Neon Rainbowfish

Rainbowfish are extremely well known throughout the fishkeeping hobby, but have any of you ever stopped to appreciate the little gems that are Dwarf Neon Rainbowfish?

In nature these gorgeous little fish tend to be found in the fast flowing rivers of Indonesia. They tend to spend the majority of their time shoaling amongst the dense vegetation and tree roots surrounding the river, so the use of Spiderwood, Bogwood, and plenty of live plants is encouraged when looking to build a set up to accommodate these fish. The rapid flow of the river can also be recreated in an aquarium setting by adding a wave maker to your tank as well.


Most Rainbowfish don't tend to enjoy brighter lighting conditions, so to diffuse this we would recommend adding some floating plants to the surface of the water to provide a bit of coverage. Stemmed plants should be arranged in such a way that creates plenty of swimming space in the centre of the aquarium, but also still gives plenty of spaces in which the fish can weave in and out of as they please.



Dwarf Neon Rainbowfish are a warm water tropical species, so should be kept at temperatures between 25 and 28 degrees. They should also ideally be housed at pH between 6.5 and 7.5 to keep them as happy as possibly in your aquarium. This species of Rainbowfish is so called due to its small adult size (in comparison to other Rainbowfish species) of around 8cm.


These little crackers are generally considered a community species, meaning they can be housed well with other peaceful and suitable fish which share the same needs as they do. Good examples of tank mates for them include other species of small Rainbowfish, Tetra, Danios, Barbs, Dwarf Cichlids, freshwater Gobies, and Corydoras. Dwarf Neon Rainbowfish can become quite shy if housed in a sparsely planted aquarium in small numbers so ensuring there are plenty of plants available and they are kept in a shoal will be key to getting the best out of them.



These fish are omnivorous and will accept a wide range of dried foods. Frozen and live foods should be offered regularly to help keep their natural colours bright. As they grow you may notice some of the fish become slightly brighter than the others and will develop some very beautiful colourations (this will be male fish maturing). They may begin to show off to the ladies of the tank and start behaving slightly differently when they are ready to mate. Rainbowfish scatter their eggs when breeding, so don't worry, it is very unlikely that you will get any babies from their scatters, unless you are purposely trying to breed them.



If these fish sound like the interesting new addition you've been waiting to add to your aquarium, why not pop into your local store and take a look at them in person (we promise the photos don't do justice to how stunning they are). Our Dwarf Neon Rainbowfish are currently on a Rewards Cardholder Exclusive offer in store, so be sure to take advantage of this whilst stocks last!
