I went and finally dropped the money I needed to on the API Master Test Kit. Ouch. Good news? Everything is perfect with my water. Though I was pretty sure about that because of how awesome my fish look.
But when I was paying, the employee (at Petsmart) and I had a brief conversation about bettas. He had asked what type of fish I had since I was buying frozen bloodworms as well. He seemed surprised I was buying a test kit for a betta. Just a betta. He talked about how he had his fish in just a glass vase and it was perfectly happy. It is even more frustrating when employees of petstores treat their own pets badly because they can get everything they need at work! And probably at discount too!!!
