Ecology Summary - Copella arnoldi

Língua:

Ref. principal	Mills, D., G. Vevers and D.L. Mills, 1989
Notas	Occurs in groups at the surface of small creeks with clear waters. Also found in ponds where it is found together with Rivulus (Ref. 27188). Feeds on Ephemeroptera larvae and ants (Ref. 12225); also on worms, insects and crustaceans (Ref. 7020). Known among aquarists by its unique breeding behavior and parental care: male and the female line up side by side at the surface of the water and jump together out of the water, to spawn. The fertilized eggs are then laid on the underside of an emergent leaf and the male then splashes them with its tail for about three days until they hatch, hence the popular name 'Splash tetra'. It was also observed that just before lining up to jump out of the water toward the upper glass of the aquarium, the female follows the male, touching her abdomen at the anterodorsal portion of the male several times, swimming agitatedly (Ref. 137764).
