My experience with big box store Bettas is not good & I will not purchase anymore from Petsmart or Petco & i refuse to start purchasing them from wal-Mart. While I am relatively new, IMO, to Bettas, a little more than a year experience, I find it hard to believe I am not properly caring for them. I am about to lose another Betta, a male VT who've I had right around a year, he is currently in dropsy mode which I know is an end result of something else. EVERY Betta, I've purchased from Petsmart or Petco die within 6 months to a year after bringing them home. I have tanks that are filtered & heated with some tanks having live plants & others silk. I do regular weekly water changes, feed pellets & frozen foods. I test the water in my cycled tanks on occasion & daily in a tank that may be cycling. The males share their tanks with snails, the females are in a sorority with some snails & 2 CAE's. I know I'm not the perfect fish keeper but I also know I do a darn good job. My local LFS's don't appear to be much better with how they keep their Bettas than Petsmart & Petco but I'm going to purchase one & see if they may be better bred. OK, I'm done with my rant.
