If he thinks it worth 10k why not find out what sex it is and build a big ass pond and throw in a couple of the opposite sex for it to play with and see what happens?
Thanks for posting the pics. I watched the other thread for a picture. Definitely a cool fsh but it is just a fish and no fish is worth that kind of monsy. They live a while and then die. Should be somewhere where more people could see it and appreciate it.
