The Mosquito Rasbora are a wonderful, colourful addition to a smaller aquarium.
They are a shoaling fish and shouldn’t be kept in groups smaller than 6. The larger the shoal, the more natural the behavior and the brighter their vibrant red and orange colouration.
Endemic to South-eastern Borneo, they are the perfect shoaling fish species for a soft water nano tank. We advise providing a low-flow filtration, dark substrate and lots of dense planting. Smaller varieties of Anubias, dwarf Amazon swords, and carpeting plants such as Dwarf Hairgrass work well. They will swim around the middle/top area of your aquarium providing a constant dash of colour in contrast to the backdrop of the plants.
Mosquito Rasboras accept a variety of foods but they are a Micro-predator and prefer to eat a mixture of live foods (newly hatched brineshrimp, small Daphnia and microworms) they will however happily accept dry foods such as crushed flakes or micro-pellets and take frozen foods.
Breeding these Rasbora is challenging but not impossible. They are egg scatterers and a suitable breeding tank should be provided.
Females lay small numbers of very small eggs and the pair provide no parental care whatsoever. They will eat their own eggs, given the chance. In a mature, well-planted aquarium some fry may survive to maturity if they avoid any adults. However, a larger number may be raised by removing plants along with eggs from the adult’s aquarium to a separate one filled with water from the original tank. Newly hatched fry are tiny and once they have absorbed the yolk sac need tiny foods such as infusoria and baby brineshrimp to survive.
