Splashing Tetra owes its common names to its breeding habits, which are quite unusual. This fish lays its eggs above the water line. The male and female jump out of the water together and cling to the underside of an overhanging leaf. The female deposits and the male fertilizes several eggs on the leaf. They repeat the performance many times until all the eggs have been laid in this way. The male then keeps the eggs moist by spraying or splashing them until they hatch. All other members of the genus breed in more “traditional” ways (see C. metae).
