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. They 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.

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.
