Tropical Freshwater Fish


Species in this group are sourced from Tropical regions throughout the world, for this reason they are best kept in heated aquariums. This group covers a large range of species and consists of many weird and wonderful species such as Elephant Nose and Black Ghost Knife Fish. It also includes other species such as the popular Neon Tetra – perhaps the next most popular aquarium species after goldfish!

Due to the wide range of species it is hard to make generalisations as to the keeping conditions and diet. However, most species are suited to a temperature of 22 – 26° C, a pH of 6.5 – 7.0 and general hardness of 50 – 100ppm. Many larger species will be aggressive or predatory and may not be suited for community tanks. The majority of the smaller species are well suited to community tanks, but for more specific information, consult the species care sheets.

You’ll find information about a popular sub-section of Tropical fish, called Livebearers, when you visit the dedicated Livebearer Fish care page.
