Well, the first thing is you bought it because you liked it. Now learning more in depth about koi in the future, then looking back I think you would have past on this Showa even if it was $15. I think at $30 you could have gotten a tosai with more pattern. The quality is so-so as well as the conformation, but as tosai you look more for the pattern. JMHO.... But, for now study what you have and on to your next selection of Showa to try your luck on.
