Splashing Tetra (Copella arnoldi)
Splashing Tetra is a slender, upward angled surface tetra famous for one of the most remarkable breeding behaviours in freshwater fish. Pairs leap from the water to deposit eggs on overhanging leaves, and the male then splashes them to keep the clutch wet until they hatch.

The Splashing Tetras are absolutely fascinating to watch. I’ve seen them jump and splash the eggs on the leaves, which is a rare and beautiful sight. They thrive in a blackwater setup with dense vegetation and are peaceful with other species.

I bought a group of these tetras for my biotope tank. Their coloration is subtle and elegant, and they occupy the surface layer well. The breeding behavior is something I’ve never seen before and it’s truly captivating.

They are active and add a lot of visual interest. I had to adjust the pH slightly lower to match their preference, but once I did, they settled in well. The jumping behavior is a highlight of the tank.
