Well after the horrifying conditions I found the bettas in petco in last week, I emailed them, they forwarded my email (which included pictures and a video of the condition of the bettas in the store) to the manager and he proceeded to call me the next day. He was pleasant enough on the phone but definitely annoyed. He told me they were going to keep a better eye on the bettas and take them all off the shelves and check them all over and make sure they are all healthy, and blah blah blah. And then he proceeded to reprimand me for taking a video in his store, So I informed him that I would HAPPILY take it down if the conditions of the fish improve.
So I went back into today, exactly 1 week after that phone call, and I am not happy with what I saw! The bettas all looked bad in some way. They were stressed out, had color loss, ripped fins, beginning stages of fin rot, clamped fins, bloating, etc. There was one dead baby. I do not believe they checked them at all, nor do I believe that any sort of water changes have been done since the last time that I was there!
I brought home 2 from petco today and one from petsmart.
The first one from Petco is a red crowntail male who has an awful internal bacterial infection. I don't think he's going to make it through the night, but I'm going to do everything I can for him. I've named him Cosmo
The ammonia reading from his cup, close to 4.0ppm
The second is a little veiltail that my friend fell in love with, he's in bad shape, but I think he might make it. His name is Martini.
His ammonia was also around 4.0ppm
and the boy from petsmart is an extremely skinny doubletail, but he's active so I think he's going to be fine. Meet Chai
His ammonia was around 0.50ppm
