Glad you were able to get her to eat! Awesome stuff with the bbs in qt.
I wanted to mention something as a reminder for all of us. When we go into the LFS regardless if it's a first time there or been going there for years, we need to ask specific questions. Try not to get to caught up in the moment. I don't mean general care instructions we can pull from LA. I mean Questions like... Is it currently eating? Yes? Oh good, what are you feeding it? The next answer you get will tell you if your bringing this fish home. Always ask question and make it the right ones. You could be super smart in this hobby forget to ask a simple question and be suddenly faced with a problem. If the fish isn't eating the food you can provide just resist the urge to buy it. It may just be that specific fish and not the species. For instance, my LFS just started getting pellet eating red scooter dragonettes.
