Pristella maxillaris, commonly known as the X-ray tetra, is a small species of freshwater fish belonging to the family Characidae. It is notable for its translucent body, which allows the internal organs and skeleton to be visible, resembling an X-ray image. This unique feature makes it a popular choice among aquarium enthusiasts.

Description

Pristella maxillaris is a small fish, typically reaching a length of about 4 to 5 centimeters. Its most distinctive feature is its transparent body, which provides a clear view of its internal structure. The fish has a silver body with a yellowish tint and a striking black and white pattern on its dorsal fin. The caudal fin is forked and often displays a reddish hue.

Habitat

The X-ray tetra is native to the coastal rivers of South America, particularly in the Amazon Basin, Orinoco River, and Paraguay River. It thrives in a variety of water conditions, from clear to brackish waters, and is often found in slow-moving streams and rivers with dense vegetation.

Behavior

Pristella maxillaris is a peaceful and social species, often found in schools. It is an omnivore, feeding on a diet of small invertebrates, algae, and plant matter. In the aquarium, it readily accepts a variety of foods, including flake food, frozen food, and live food.

Reproduction

The X-ray tetra is an egg-scatterer, meaning it releases its eggs into the water column, where they are fertilized externally. Spawning typically occurs in the early morning, and the eggs hatch within 24 to 36 hours. The fry are free-swimming after about 3 to 4 days and can be fed on infusoria or finely crushed flake food.

Aquarium Care

Pristella maxillaris is a hardy species, making it suitable for beginner aquarists. It prefers a well-planted aquarium with plenty of swimming space. The water should be kept at a temperature of 22-28°C (72-82°F) with a pH of 6.0-8.0. Regular water changes and good filtration are recommended to maintain water quality.
