Not all bettas can be shown off with the perfect, non-damaged fins. AB may have some beauties, but do not expect the 100% perfect. Personally I would argue about that ThaiTyBeta guy, rather than BasementBetta. Do his fish look healthy? Yes. Do they display stress lines? No. Are their gills inflamed, blackened, or scarred badly? No. Do his fish have ich, or other noticeable parasites? No. Do you think his fish would arrive safely if he were to ship SICK fish? NO.
Shipping sick fish is dnagerous. I was shipped healthy fish and 2 weren't doing great the first couple of days. Imagine if they were sent sick?
Breed for the breed, not for the money; the words any REAL breeder would understand.
You must know nothing in order to know all, for all is nothing and nothing is for all.
