Betty No, that's just "web talk." I imagine the person is theorizing that one should not expose baby fish to pathogens unnecessarily. An old tank with "stuff" growing in it sounds great to me. The average fish tank has enough small things (the little worms and cyclops, etc. that people are always complaining about) to feed a bunch of baby koi in their early days. They are actually great scavengers. Steev --- Betty Goetz <haika@drizzle.com> wrote: > I'm excited! Now, I've been reading up on growing out koi fry and read > something that concerned me.
