The X-Ray Tetra is a small fish that many people like. Its see-through body makes it look cool. These fish live in groups and swim in the middle of tanks. They eat small bits of food and get along well with other fish.

The name Pristella maxillaris comes from Latin. Pristella means “saw” and maxillaris refers to the jaw. This name was given because of the fish’s shape and mouth.

In pet stores, you might see them called X-Ray Fish or Golden Pristella Tetra. They belong to the Characidae family, which includes other tetras and piranhas.

These fish come from South America. They live in slow-moving waters with plants. In the wild, they eat tiny animals and plants. When kept as pets, they like flakes, small pellets, and frozen foods.

X-Ray Tetras grow to about 2 inches long. They can live up to 5 years with good care. The fish do best in groups of 6 or more. They need tanks that are at least 10 gallons big.

One fun fact is that these fish can change color based on their mood and surroundings. When happy, they show more yellow on their fins.

Scientists first wrote about X-Ray Tetras in 1894. Since then, they have been popular in the fish hobby. Their clear bodies let us see their insides, which is why people find them so interesting.

Some fish keepers have bred X-Ray Tetras at home. This helps protect wild populations. The fish lay eggs that stick to plants. After a few days, baby fish hatch and start to swim.

X-Ray Tetras are peaceful and active. They like clean water between 75-82°F. These fish don’t need special care, making them good for new fish keepers.

In research, scientists have studied how X-Ray Tetras grow and behave. Their clear bodies make it easy to watch their organs work. This helps us learn about fish health.
