There's a silver arowana at my lfs that has a pinkish color to it. When i asked one employee about it he said it was just dying, but when i went back a week later it was still swimming around on the surface. a different employee that day said it was "dyed", whatever that means. has anyone ever heard of this? it seem totally messed up if that's the case, but i was curious what the heck was going on there.
