No. Don't have time for mock judging. Fish are judged and they win points toward year end awards. Shows are exhausting work for those that put them on. And there is the expense of ribbons and the time it take to judge. Pet shop bettas are going to fall pretty short of the standard.. and we are not into awarding subjective *pretty fish* awards. Just not how it is done. You do not see dog, cat or horse shows for *pet* types. Westminster is not going to have a mock judging for people to see how it is done. The expectation is if you are going to enter, you know the rules and how it is done. Shows are about evaluating the best of the best in anything. Why should it be different for fish?
Some shows may offer a local pet class for walk ins and it becomes peoples choice for the winner. Again, most judges do not have time to look at them.. But for anything else the reality is are you going to spent money to send a pet fish to a show and back home? I have at least $100 in every show with shipping and entry fees. And I do it every other week during the season.
You want people to tell you you have a pretty fish, it does not belong in a show or this section of the forum. Enjoy him but accept you do not have show quality. You want to seriously breed good fish to show.. then this section is for you. The expectation is to see fish pretty close to the standards for evaluation here. Otherwise you run the risk of having your pretty fish ripped apart fault by fault.
