It is endemic to the Mamberamo River basin in West Papua in Indonesia[2] and common in the aquarium trade.[3] IntroductionThe dwarf rainbowfish occupies small, slow-moving tributaries in regions with rainforest.[2] It generally reaches up to {{convert|5|cm|in|abbr=on}} in length,[2] but there are reports of individuals up to {{convert|8|cm|in|abbr=on}}.[3] M. praecox is considered to be an omnivorous species. Males tend to be brighter in color and have deeper bodies than the females. This species' is considered to be an egg-scatterer, so it is easy to breed.[3] Their bodies are bright blue and iridescent, and their fins are colorful. This species is active and is known to jump out of water.[4] They are native to a tropical climate. This species is harmless to humans, and is used commercially for aquariums and commerce.[5] They are known to be found in freshwater environments within a benthopelagic range.[6] References1. ^Allen, G. 1996.
