One of my pineapple males won the pairs class with a pineapple female, and then went on to win BOV Shortfin Male (out of 23 in his division).
I was scolded by one of the judges to put his brother into the traditional PK class (instead of the form and finnage class) - she said that his brother would have won the show! Just goes to show you that how a fish performs at one show, under one set of judges, could be very different under another set of judges. Always review the standards carefully and try to put them in the class that gives them the best chance, no matter what.
Our show HMPK ladies also did well, and placed 1st and 3rd in the same class (out of 7). My tiny little intense yellow girl was finally big enough to go to the show - she was barely 1.25". The clean yellows in this spawn grew MUCH slower than their red or pineapple counterparts.
