Has anyone heard of such a thing??? I had two arowanas 8" and 10". Everything is well, and I'm sure they were silver when I bought them. Then I bought a third arowana, and it wasn't untill then that I realized how dark the other two had become. My first thought was that it was the "arowana pellets" I was feeding them that is supposed to enhance there color. Because I was so preoccupied with how colorfull they were becoming I didn't notice how NOT silver they were also becoming. This is just one of my theories. I have stopped feeding the pellets about 2 weeks ago or less, but they still seem so dark. I do regular water changes and all the fish are hungry, healthy and aggresive. No flicking of the fins, just normal arowana behavior. I can't see any negitive signs from them. Any ideas??? THanks, Brian (OSPY)
