The petland near me is pretty horrible. I am just not going to go in there anymore, I just can't. I always end up leaving with a betta that tugs at my heart. I definately QT all bettas from there for a month before going into any divided tanks. The thing is, they have lovely bettas in all colors and tail types. They look great when they come in, and then they slowly deteriorate and it is so depressing. I don't know how often they change the water but it always looks filthy. However, all the bettas I've gotten there (except for the really sick one that didn't make the trip home) are doing great. I guess it's survival of the fittest there. The employees seem surprised when I tell them how well my fish are doing. They're like, you're the only one who seems to have luck with bettas. Its not luck! It's warm clean water and TLC!
