We have several(6-8) Koi in our 3.5 acre pond. They are now between 15"-24" and fat as all get out. We do feed our Cats, bluegills and Koi pellets everyday. My wife has actually named each one of them. We also have 4 Grass carp that are now 3-4 feet long! I'm sure they don't do much to keep the weeds down, but I love seeing guests surprise when they see one lounging on the surface.
I have been to Zetts many times and quite frankly they are not very customer focused. I would love to find some Talapia in the area. I could use them! Good luck Catmandoo
