the amazing splash fish

THE AMAZING SPLASH FISH (Friday Church News Notes, October 19, 2007,, 866-295-4143) - There is an interesting fish that lives in South America called the splash tetra (Copella arnoldi). It is a small elongated fish about 3 inches long and lives near the banks of slow-moving rivers with heavy vegetation. The male finds a suitable leaf hanging over the water and waits for a female to join him. They then position themselves side by side and leap out of the water at exactly the same time and stick to the leaf. The female lays 6 to 8 eggs and the male fertilizes them, and they drop back into the water. This process continues until they have laid and fertilized about 200 eggs. The female then leaves, but the male stays there for three days using his tail to splash water onto the eggs every 10 or 15 minutes so they won’t dry out. He does this until the fry hatch and fall into the water. There is only one fish in the world that does this neat trick.

I would like someone to explain how this amazing process could have evolved. First of all you would have to evolve a male and female tetra fish with the amazing capabilities of breathing underwater and reproducing offspring and such, all of the incredible complexity of the fish at the genetic level. Then you would have to evolve the splashing business. Assuming one fish learned to jump out of the water and stick to a leaf, how did two of them learn this at exactly the same time? It would have been necessary that they perfect the trick the very first time or it would have been meaningless. If only the male jumped or if only the female jumped or if they both jumped but did not lay eggs and fertilize them or if they jumped and laid and fertilized eggs but the male didn’t keep them wet -- nothing would have happened. And how did that incredibly clever and gymnastic pair then pass this amazing process along to their offspring who were not around to observe it?

Anyone care to comment?
