Diamond Tetra (Moenkhausia pittieri) Species Profile & Care Guide

Diamond Tetras are a peaceful shoaling fish that visually improves as it matures. These fish can tolerate harder water, but should only be kept in soft to medium water conditions over a long time.

The Diamond Tetra is best kept in aquariums with plenty of plants, open spaces, and subdued light or shade, with a dark bottom to show off their beautiful colour.

These tetras are an excellent small shoaling fish but may nip at elaborately finned fish such as Guppies, Angels or Siamese Fighters.

These Tetras have a silver body, and the dorsal and anal fins are purple. The eye has a noticeable mark of red above the pupil, and there is a dark stripe running across the midline of the body. They get their name from the bright, shimmering scales along the flanks.

Natural Habitat of the Diamond Tetra

The Diamond Tetra is found only in Venequela's Lake Valencia and the surrounding waters. Here they inhabit slow-moving streams with abundant vegetation and leaf litter.

Because of industrial and agricultural pollution, Lake Valencia is subjected to regular algae blooms which usually isolate the Diamond Tetra in shallow, vegetated parts of the lake and several of its slow-moving tributaries.

In an aquarium, Diamond Tetras will eat most fish foods you offer them, and this includes flakes, granules and small pellets. They will also eat frozen and live foods such as Bloodworm and Daphnia, and these will benefit them and bring out the best condition and colour.

Sexing the Diamond Tetra

Males have more extended, and a more distinct large dorsal fins than females and the females are more rounded and not as vibrant as the males, The male's scales are also much more reflective than those of the females.

Breeding the Diamond Tetra

Diamond Tetras will require a separate breeding tank, this should be dimly lit with soft water, and the temperature should be raised by a few degrees then what they usually have. The tank will also need to be heavily planted to provide shaded areas for them to spawn in.

For the healthiest and best fry, you will need to choose your strongest female, and the best-coloured male and place them into the breeding tank and continue to feed them with rich food; this includes live food.

The Diamond Tetra will usually spawn in the early morning, and the female will lay a couple of hundred eggs which the male will fertilise. Once this has taken place, you should remove the parents, as they will consume the eggs.

After about 24 to 36 hours, the eggs will start to hatch out, and 3 to 4 days after that the fry will become free swimming, the fry grow relatively quick.
