Water conditions and arrangement
Moenkhausia pittieri is an undemanding fish, although it does not like increased water hardness or alkaline water. As it is a herd fish, it's necessary to introduce at least 6 individuals into the fish tank. The minimum tank size for such a group is 100l. Diamond tetras prefer water temperature between 24-27 Celsius degrees and the pH 6,5-7. A gentle water flow from an external filter is recommended. These active herd fish need a large open swimming space, but not so many aquarium plants. The water should be soft and acidic, preferably with some tannins. Lighting should be not too intense. For the arrangement, you can use roots, leaves and pieces of wood. Diamond tetra thrives among such decorations.
To ensure the proper growth and development of the fins, diamond tetra must be fed with live food such as daphnia, bloodworms and mosquito larvae. If live food cannot be obtained, frozen food may be used as well as dry food. They often like eating aquarium plants which should be also mentioned.
Breeding diamond tetras is possible in normal aquarium conditions. Before spawning, the diamond tetras should be fed particularly well so that they gain weight and increase in size. To encourage the breeding pair to spawn, raise the water temperature to around 27 degrees Celsius and darken the breeding tank. It is also a good idea to provide the fish with a sufficient amount of dense live plants. During and after spawning, the light supply to the aquarium should be gradually increased to imitate the light in natural habitat. After laying the eggs, the parents should be caught as soon as possible and moved to separate tank to prevent them from eating the eggs. The fry hatch after approximately 36 hours. In the first days of its life, the diamond tetra fry should be fed with rotifers, and later introduced with other fish food.
Moenkhausia pittieri is a stunning tetra species which can be a beautiful addition to any aquarium because of its peaceful attitude to other fish. These fish thrive among live plants in all biotope aquariums of South America (not only Lake Valencia biotope) which is an additional advantage, especially that diamond tetra care is easy comparing to other freshwater fish. We strongly hope that diamond tetras will be the great tank mates for your current stock soon!
