Microhabitat use and feeding behavior of the rainbowfish Melanotaenia duboulayi (Castelnau) were investigated in a slow-flowing stream adjacent to riparian forest in south-eastern Queensland, Australia. Fish were more abundant in vegetated areas, but did not enter dense Vallisneria beds, where predators were observed. In sunny conditions shoals of juveniles occurred near the water surface feeding floating material on the surface, but larger fish tended to occur at the bottom near submerged vegetation, often utilizing the overhanging aquatic plant community as a refuge and food source. In the middle of the day, juveniles and small fish seemed to show behavioral thermoregulation at the surface in the warmest site. Under cloudy conditions, however, fish of all sizes preferred deeper water. The present study suggests that in still and sunny pools thermal change caused by sunlight influences the microhabitat choice of small fish. A field experiment using a kingfisher model implies that fish swimming at the surface could escape from aerial predators in sunlit conditions by responding to moving shadows, but could not do so under cloudy conditions.

Rainbowfish are a family of small freshwater fish that get their name from their bright, iridescent colorations that change shades in different light settings. In recent times rainbowfish have started to gain popularity amongst aquarists for both their beauty and relatively hardy nature. They are also a relatively small species of aquarium fish with most species reaching only a couple of inches in length. In fact, the largest species of rainbowfish only reaches around 8 inches in length. Rainbowfish are an extremely peaceful species of fish and make excellent additions to community aquariums. My main question is, if I choose Firemouth could I also keep a schoolDwarf Rainbowfish Melanotaenia praecox or is this fish too small to becompatible?

If you want to, you can set up a separate breeding aquarium for your fish. A breeding aquarium doesn’t have to be as big as a normal aquarium. A majority of the rainbowfish species will breed in aquariums no larger than 40-50 litres (11-14 gallons). Cover the bottom with a thin layer of gravel and include java moss or spawning mops to act as spawning sites. If you use mops, make sure that they almost reach the bottom of the aquarium since many species of rainbowfish are accustomed to spawning roughly one decimetre (4 inches) above the bottom. Aeration is mandatory, but a lack of filtration can be remedied by small and frequent water changes. Rainbowfish is group of small and usually colourful fishes found in the southern hemisphere. They did not grew popular among aquarists until fairly recently, which is actually a bit strange considering their beauty and sturdiness. Some species stay below 3 cm in length even as adults, while other species can attain a length of up to 20 cm. An additional plus with Rainbowfish is that they leave plants alone – they will not eat them nor uproot them. Rainbowfish is also an excellent choice for aquarists who like their fish to spawn in the aquarium.

Rainbowfish belong to a subfamily named Melanotaeniidae and are found in Australia and New Guinea, as well as on some of the Southeast Asian Islands. Rainbowfish are closely related to the Blue-eyes of the subfamily Pseudomugilinae and both subfamilies belong to the same family, Melanotaeniidae, according to a taxonomic revision made by Joseph Nelson in 2006. The order Atheriniformes – the order to which Rainbowfish and Blue-eyes belong – has undergone a lot of changes during recent years and is expected to see some action in the years to come as well.

Since Rainbowfish are peaceful creatures they can be kept in community aquariums with other non-aggressive species. Really small species can however find it hard to compete in an aquarium with larger species and should therefore be kept in their own aquarium, or together with other really small and peaceful species.

Rainbowfish are schooling fish and should be kept in groups consisting of at least six individuals, preferably no less than 10-15. This is not only beneficial for the fish; a large school of shimmering Rainbowfish is also much more stunning to look at than a few shy individuals that spend most of their time hiding. Keeping several males together will also make them develop more vibrant colours since they need to compete with each other for female attention.
