Yikes fishin, you sure got a bargin on your koi.
How old are your koi? ...and how many do you have?
All ours were purchased in
1997 and 1998...so they're 13 & 14 years old.
we also have two goldfish, one goldfish is 14 year old.
I'm counting on my fingers here, I think we purchased
about 8 or 9 koi, the rest are our spawns.
...and yes they're between 24-26" long.
Also most were between 3.50 and 7.00.
Terminator, the big golden butterfly was 15.00. (we splurged on her)
I flipped when I saw her wings and tail, and had to have her.
I'm not sure of this statement, but it has been our experience that the
butterflies are extremely active...it probably is because all that
tail swishing makes them highly visable.
In any case the following year in 1998 -- we added another section to
the pond. The head groundskeeper calls it the Dog Leg...it's a section that's
6 ft wide x 13 ft long, so they do have a decent amount of swimming room,
and as our videos prove they sure love to swim.
Just came back in with an edit cause I didn't answer your predator question.
We have a trap set all the time and catch and relocate racoons all the time.
We catch a lot of possums too, but release them into the yard cause we
think they are fish friendly. we actually have an outdoor pet possum.
as far as birds of prey...we're surrounded by huge oak trees and the birds don't
feel secure enough to land in our yard.
