Feeding fish with other than fish food?

[rubyduby]

I have given my goldfish cheerios just before I cut off feeding for the winter and for their first feeding after the water warms up enough (this was all from recommendations from forum members… this place is so great)
I don’t give them much though as I think they need better stuff. I just grind a few up between my thumb and fingers and toss it in.

Mine get a bunch of Italian Parsley tied with Jute and they strip the stalks clean within minutes...They get this almost every night since my pond is on the small side (about 900 - 1000 gallons) and my shubies are getting very big ....Every afternoon they get Dainichi pellets and Tetra Vibrance sticks....So far everyone is very healthy looking and acting

My fish also like to eat watermelon! This is something I never expected! I have been feeding them fish food from the beginning. One time my friend recommended me to feed them watermelon, and since then, I have been feeding them watermelon.
