Diamond Tetra (Moenkhausia pittieri)
A stunning little fish, as its perfectly chosen name suggests. Peaceful and serene, providing a sensational display when kept in a shoal of six or more, then at feeding time they go nuts! Diamond tetras love their food, and will eat anything, with real enthusiasm. They will eat all kinds of live, fresh, and flake foods. Also brine shrimp or blood worms as an occasional treat. They will also have a nibble on vegetable treats such as courgette or lettuce put in the tank (though remember to remove leftovers!)
They are found wild in South America, notably in Lake Valencia in Venezuela, and the rivers and tributaries nearby. Despite their glamorous appearance, diamond tetras are easy to keep in a well maintained tank, and will even breed from time to time in the right conditions (scattering eggs among plants, like most other tetras. These take between 24 and 36 hours to hatch). The parents (and other tank mates) will eat the eggs, or if it comes to that, the fry, so make sure they are removed into a safe environment if you want to have babies!
