Pristella Tetra

The Pristella Tetra can be a really good fish for the freshwater fish beginner. These Pristella tetras are fairly hardy and should do well in a somewhat broader range of water parameters than other tetras. The Pristella tetra is very peaceful when kept in small schools of 6 or more. However, they may become skittish if kept with larger tank mates.

Physically, these Pristella Tetras get to be about 2 inches (5 cm) and they are sometimes called the X-Ray tetra because of its almost transparent body. Look for the signature black stripe across the middle of the dorsal fin.

There is an albino Pristella tetra (golden x-ray tetra) that will sometimes be available, but it is not as common as the regular Pristellas.

It's always a good idea to keep any new fish in a quarantine tank for a few weeks for monitoring before introducing them into your main tank.

This tetra is a decent eater and will accept smaller fish food including flakes, frozen, freeze dried and live foods.

Pristella Tetra Tips

From: Chris
Great little fish, all 5 survived our water problems and they are great to watch with their bright striped fins and rather round bodies. In our small shoal there is a quite a size range from a little one to two quite chunky ones but they all seem to get along really well.

The X-ray Tetra I have is the Hardiest fish I have ever seen! I lost power for about 5 days and he survived without a heater!
