Wow...First off I would just like to say that you have a very Beautiful Pond....You did an excellent job on it...

I feed my fish 1-3 times a day as much as they can eat in around 3 minutes....I have heard that you can feed them up to 3 times per day as much as they can eat for 5 minutes but i dont feed them that much....Remember that the fish will prolly eat nonstop if you keep feeding them..They dont know when to stop so I know overfeeding them isnt good for them..I am no Expert but this is just what I have read on Numerous forums and sites....The fish really dont need much food from us anyways...They can pretty much survuve off of the bugs that land in the water and off of the Algae in the pond...Hope this helps...I really love your pond...~raskal

Looks like they also got lots of plant and roots to nibble on....

I feed my fish once or twice a week and yes, once they learn what it is they gobble it up. My thought is that they will eat algae, bugs, and fish eggs. They will grow more if you feed them more, but my six 7-8" goldfish, comets and shubunkins are about all my 300ga pond can hold...anyone want my 5 babies?
