By tying food pellets to the end of string algae, over the course of
several
months I trained my Koi to eat string algae. I no longer have to feed
them,
but have noticed that their fins are getting longer, narrower, and have a
greenish tint.

Let's see, today is what, April 1st?

LOL! You had me until the fins part :-)
