Buying online from random companies sure is convenient, but I am seeing a lot of threads here where people have received deformed or unhealthy fish, mixed with the healthy ones. The sellers give you the number of fish you've ordered. There is often no quality control.
If you go to a store to buy fish, you can have an active input into what fish you get. Choose carefully. Study the tank. If the seller nets a fish that looks atypical, refuse it politely. If the fish looks diseased, don't buy from the aquarium. It doesn't matter how much you want the species. Other stores will have it, or you can wait til the next shipment comes in.
If you take pity on a fish, don't put it in your main tank. Have a tank for it, alone. It sounds harsh, but that guppy with the bent spine can have communicable TB, or a bacterial, parasitic or viral infection that can kill your entire tank.
Years ago when I caught fish for a store, I tried to sell the best fish. The owner of the store would refuse to pay for poor specimens, and the wholesalers he dealt with respected him. We got very few sickly fish. But if a customer was passive - a person who asked for 6 swordtails and then started looking at other tanks, etc, they got the first six fish caught. If they paid attention, I was instructed to net trap the fish against the glass and let the customer approve of each individual. We survived on regular, repeat customers buying healthy fish and returning again and again for food, supplies, etc. The business is very different now, but the need to pay attention, say yes and no, and to work with the person with the net is still as important. When you go to a store, make your own choices, carefully. Talk with the seller.
