Who told you that fish is a short body aka bonsai? To me, it doesn't look much like a short body but just a body that is really bulky and packed a lot of muscle structure. Not like the long body either, but that is not a short body either.
$200 for that guy, I'm guessing that Red ZZ mix(real Red ZZ don't have water KOK) is okay looking. The KOK itself is decent for it's size. That would be my guess why it put what the price is. If your going for KOK only, it might be worth it depends on how scarce your budget allows you. But talking about quality overall, KOK is nice but the fish itself is okay to me.
But for this...I got to say...it's your call. If it was me, I would try to drop it to $100.
