5 Interesting Facts About X-Ray Tetras

X-Ray Tetra

Here is an X-Ray tetra showing off its insides.

Today I want to write about a tough little fish with very strange skin, the X-Ray tetra.

Here are five interesting facts about them:

  1. These tiny little fish grow to about 5 cm long.
  2. X-Ray tetras get their name from their see-through skin that shows their bones.  You can also see the eggs inside a female at breeding time.
  3. Even though they look cute, these guys are actually predators, mainly eating small worms, insects and crustaceans.
  4. At breeding time, the females lay 300-400 eggs.  The babies (called fry) hatch within 24 hours and start swimming around within a few days.
  5. X-Ray tetras are found in the Amazonian waters of Brazil, Guiana, Guyana, and Venezuela in South America.  They are tough little fish and can survive in saltier water close to the coast as well as the freshwater of the Amazon.  They are very common and are regularly kept as pets.

I hope that you found these facts interesting and learned something new.
