Pet Supplies Plus in my area is the absolute worst place i've ever tried to buy anything aquatic from. They dont care for their betta's at all. I've seen numerous moldy and dying ones on just about every occasion I've visited.
As for my worst experience there...I was going in to look at their ADF's but looked at the betta's first and saw one dead and moldy, there were two employee's standing right in front of where they keep the poor guys. I showed it to them and they said "oh better get him off here before anyone else see's" and walked away. I then went into the fish room where they have even more betta's and saw one in the african clawed frogs bowl. I'm not sure what was wrong with him but he was definitely almost dead..told the employee, hoping I could take him home to try and save, but she acted like she didnt hear me. I just let it go because I was still wanting to get an ADF, but when I asked about them using the same nets between the clawed and dwarf's she said yes, was clueless about why she shouldnt do it, and when I informed her of why she kind of stuck her nose up at me and her only reply was "ok, suuure" so I walked out without buying a dang thing and will never go back in again. I've written numerous e-mails to corporate about how they need to hire employees that know atleast a little about their live animals, that I've applied numerous times, have a lot of experience and have never recieved a call, and that if they dont want to hire someone they atleast need to give basic training to their employees. The only reply I've ever gotten was that that they were passing it on to the franchise owner of that store or the manager/district manager there...Never a word from anyone there.
But my petsmart is actually somewhat knowledgeable. They actually hire people that know what they are talking about with their fish, although some of them are a little clueless on betta care.
Sorry for such a long reply. but pet supplies plus really makes me mad!
