We all know that betta fish neglect in fish stores is a real problem. There are some stores that are literally a hell hole. Even though they are kept in cups, I still feel there is something to be done to keep them reasonably healthy. I went in the morning to a petco, all the employees just calmly lounging around, gossiping, joking, while the bettas are filthy- about 100 of them, fin rot, dead-rotting fish, dropsy, clamped fins, open sores, it was disgusting. Whenever they even swam, all the waste would stir up and it was gross. ALL OF THEM were like this. So I left, didn't buy anything, I went to petsmart. They only had about 50 bettas, all super clean and reasonably healthy. This store CONSISTENTLY keeps their bettas clean and does not overload on them. I also notice that when they only have a few left, they put them on sale and get rid of most before receiving the next batch. I decided it was just as important to send positive feedback as well as negative because it motivates the employees to do a good job, because we actually notice the difference.
I encourage everyone to send a positive email to corporate, to acknowledge a store that does a good job. Also, let the employees know if person that you appreciate it. Also choose to buy your supplies from these stores.
