The Dwarf rasbora (Boraras maculatus, formerly known as Rasbora maculata) is the species of genus Boraras that is known for the longest time in the hobby. None of these species grows bigger than 2-3 cm and thus they are perfect candidates for the so-called nano-aquaria. All like to be kept in soft and acidic water, rather dark tanks, that should nevertheless be well planted (best use swimming plants), fine live food (although they also take readily dried food) and company of their own kind.
The Dwarf rasbora inhabits the malayian peninsula, southern Thailand and Sumatra. Initially it was often thought to represent the juvenile of the much larger growing species Rasbora kalochroma, but observations of the fish in aquaria and their successful breeding left no doubt on the validity of the species.
There do exist lots of varieties of the Dwarf rasbora which may proof to be different species one day. Typical for all of them is the large shoulder spot, which is in any cases bigger than the eye. The ground coloration of the body depends on the variety and can be light orange up to deep red. Some populations have an additional black spot (all Dwarf rasboras have three black blotches: one on the shoulder, one on the origin of the anal fin, and one on the caudal fin base) on the beginning of the caudal peduncle right above the anal fin.
