Thank you all so much! I was thinking of getting around a 2.5 gallon tank, maybe one of the kits. I stopped by walmart just to browse tanks and yes they have bettas there... but I was actually very impressed with the quality of the fish section! Every tank was crystal clear, all the water was clear and clean, you didn't see dead fish floating in every tank, none had ich, they all looked relatively healthy AND they weren't overcrowded! Compared to my last visit a few years back (in Branson the walmart didn't have fish) it is a MAJORRRRR improvement! I still probably will not purchase my fish there, just supplies, but I was very impressed at the quality improvement from my last visit.
