I can totally relate. I ordered my new females from breeders on this site. I generally will tell them that I am not looking for breeding quality fish and just pet fish. The high quality ones are usually pretty expensive but many people on here will sell you some of their lower quality ones for cheaper. I honestly think you can get some absolutely wonderful gorgeous bettas that are not breeding quality. My CT is a beauty, but I can tell he wouldn't be breeding/show quality because he has a curled pectoral fin and also because he is blind... which may or may not be genetic.
I don't have a problem, however, just getting a fish from the pet store. The reason I ordered my females from a breeder is because they will be my sorority girls and private breeders GENERALLY keep all their females in one big sorority and they are also kept together longer at birth. There's also a bigger chance that they will be healthy, however, the shipping process could stress them out and cause some issues, so I am still obviously going to QT them all.
Aquabid is a good idea IMO because you will likely get better quality fish. While many of them are breeding quality, others are just lower quality ones and I've seen them go from like $1 on aquabid. I would still recommend ordering from people directly off of bettafish.com just because the ones I order from have gotten MANY good reviews from other members here.
Maybe I'm too trusting on this site :p but I do believe that the long-term members on here are dedicated to the good health of their bettas and the bettas they sell. Anyone who didn't care about them probably wouldn't spend so much time here :p
