I'd be happy to give you the 'vague Judgement' you've asked for:
1. An adult would have waited to get home to get a better picture before posting.
2. An adult would not have posted the azz end of a 7" koi and asked for evaluations re: show potential.
3. Trying to evaluate this pic of this koi for show potential is a complete waste of time.
But then, with 3,500 posts on three koi boards you should've known what the judgement would be -- shouldn't you?
