Red phantom tetra
Hyphessobrycon sweglesi




Living in smaller rivers and flooded forests
The red phantom tetra is a small fish that lives in smaller rivers, streams, and flooded forest areas around the Orinoco River in South America. The fish is endemic to the Orinoco River, meaning it is only found naturally in this one place. It thrives best where it can hide among aquatic plants, and likes to live in shoals. The red phantom tetra is not yet an endangered species, but the rainforest around the river where the fish live is endangered by deforestation and illegal mining. Therefore, there is still a risk that the red phantom tetra will decrease in number in the future.

Hatches after 24 hours
The red phantom tetra male has stronger colours and a longer dorsal fin than the female. He uses the colours to impress the female when it is time for mating. He swims close to the female, and the female jerks her body to release her eggs. She lays about 300 eggs, which stick to the vegetation in the water. The eggs hatch into small fry after just one day! The fry is left to fend for itself throughout its growth.
