we nicknamed him "Big Blue" i like him because i bought him for $5 at the local fish store when he was 5" long and in 3 years he's doubled in size. all my fish are mutts, lol. i just get ones i think are pretty.
i have 6 koi, and 2 goldfish in my pond, but they're outgrowing it. we just had to go out and get an emergency pond because spring is coming and they're huge, and now that its warm and they're eating again, they're going to start growing. so we got a like 6 foot diameter, 3 foot deep rubbermaid water trough to put 4 of the fish in, and left the other 4 in the original pond, which is about the same size.
my parents are going to be moving to a new 5 acre property they bought and they're going to build a huge pond up there for the fishes.
i've also got a weird peachy colored butterfly koi, Orenji Ogon, a platinum, a Shiro Utsuri butterfly, and one i'm still not 100% on either. someone else called it a Doitsu Ki Utsuri, but i'm not sure on the Utsuri, but i can't find anything better. i wonder if maybe he could be a Midorigoi?
