The fish, up close
The Splashing Tetra, scientifically known as Copella arnoldi, is a unique and captivating species native to the slow-moving blackwater streams and flooded areas of the Amazon River basin in South America. These slender-bodied tetras have an elongated, torpedo-like shape with silver bodies adorned with striking black markings that resemble splashes of paint. Their fins are delicate and elongated, adding to their graceful appearance. Splashing Tetras are known for their distinctive spawning behaviour where they lay their eggs on overhanging leaves, allowing the fry to drop into the water upon hatching.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Splashing Tetras are peaceful and shoaling fish that thrive in groups of at least six individuals. They are active swimmers that appreciate a well-planted aquarium with plenty of open swimming space. These tetras are known for their unique 'splashing' behaviour, where they jump out of the water to catch insects. Providing a secure lid is essential to prevent them from leaping out of the tank.
Tank planning
Maintaining stable water parameters is crucial for the health of Splashing Tetras. They prefer slightly acidic to neutral water with temperatures between 24-28°C. Regular water changes and good filtration are important to keep the aquarium clean and maintain water quality. Providing ample hiding spots among plants and driftwood will help these tetras feel secure.
