ThanksVery pretty.
very nice pond
re: the koi, my father's pond isn't much larger than that -- maybe 10 x 5 in a corner shape much like yours -- and has some monster koi in it that he grew from fingerlings. total population is about 8 koi between 15 and 35 inches (rough guess) and a dozen feeder goldfish that are now dark red and 4 - 6" long. some of those koi could feed a family of 6 easily. ;-)
Cuz theyre prettier and I dont have to bring it in during the winterThe hole was probably made by a mole. Maybe a starnosed mole if it was the size of a golf ball.
What do you want koi for?! When I make my pond, I'm planning on putting a longnosed gar in it. I can forget about animals stealing it from the pond. In fact, animals better watch out!
How many gallons is your pond about?
