Mavi, I was thinking about getting some between 6 and 8 inches. I love watching them grow; I also love the price when they are that small. Again, my only worry is quarantine. I'll work it out later, tho. I've still got a few months before I can add any koi.
$500000 ?!?!?! Holy smokes that's a brand new car!!!!! I know I've seen blue fin tuna go for something like that, but a single koi? It must have been a perfect tancho. I kinda want to see this half a million dollar koi.
I have one large koi who can be a bit pushy with food. Halloween. She's the largest and the piggiest. I've actually had better luck when I introdcue my koi in groups of 2. The two new guys just hang together for a bit before they find their place in the school. When I introduced one little guy on his own (Suzaku the kohaku, my newest edition) he hid for months. I would only see him around feeding time and only for a second. It took him a whole year to get comfortable with the group.
Oh. My. God. Mavi, your pond is amazing!! It's huge!!! I would love to see some pictures of your fish next summer. They must be huge!!!
Zappity- the key to cutting down on the maintenance you have to do is the long run is to not cut corners when building.
+1000000 This is the best advice! Never cut corners with a pond. It will kill you in the long run. Ponds are expensive endeavors. But if you have the time, the money, and the will, they are wonderful places to retreat.
Muffin, I'm really sorry to hear about your loss. *hugs* I would be devastated to lose my koi. But you are right to wait and research. Be sure to remind your parents that koi ponds are life-long commitments. Even if you decide to get rid of the koi, you will still have a huge hole in your backyard which is an insurance liability. I think your best bet is to find a local koi expert. There are certain quarks of the different locations we all live in which local pond expert will be best versed in. Mavi has her pond guy, and I have mine. They really make a difference. Ponds are different than aquariums. It really is best to bring in outside help when constructing it. You might also want to find a local koi pond club. They can help, too. Or a good koi forum. You'll find great advice there.
EDIT: Muffin, I did a quick search on Texas Koi Clubs and found a few. I found some based in Houston and some in Dallas. I don't know which would be closer to you. They might be something to look into, tho.
