Splash tetra

Copella arnoldi

No photo yet

The splash tetra has one of the most curious breeding habits among fishes: the pair leaps out of the water together, clings to a leaf above the surface and releases the eggs there. The male then stays nearby splashing water with his tail to keep them moist, until the fry hatch and drop into the water two to three days later. It lives in streams with plenty of overhanging vegetation, from the Orinoco to the Amazon, and eats worms, insects and crustaceans.
