This was a legitimate question that belongs in this section. It all started with someone making an ASSUMPTION that the OP intended to buy a fish to show, and not raise their own fry. The question was whether the fish was show quality, it was a legit question. The OP never took ofense to the fact that his fish was not "show quality". Many breeders start wit non-show quality fish who have a trait they like, and then they breed towards improving, the EE trait is still not very well developed in long- finned bettas therefore, it counts as a legitimate question.
If you really want only "show quality" fish to be posted here, then you need to be specific in your sticky. Put "only show quality fish here, that meet ibc standards, if you do not know what the ibc standards are, then you probably shouldn't be posting here" but since it doesn't say that, people shouldn't be nailed against the wall, not for how their fish look, but for even asking the question.
We all know basement bettas is good at what she does, trust me, we know, i know, i follow her fb page, there is no doubt there. If she feels like a question is not worth her time answering, then she should simply abstain from answering it.
