Ok, I know this idea means nothing, too bad I don't work at a fish store or wal-mart or something. But here goes. Don't you think it would be a great idea if the stores that sold bettas had them in 1 gallon pet carriers, with gravel and a plant. You could sell these "kits" for maybe ten/fifteen bucks, and I think people would buy them. I know it would take up a lot more shelf space, but how pretty would they look there in their little homes, gravel and plant included. This way people wouldn't be left the responsibilty of buying tanks, b/c you know most people always buy those little bettafront kits. How attractive would the little boys look, they would be so much more active and pretty sitting there in cute carriers, rather then barely moving in a nasty cup. They would be much more marketable, if only these stores would think.
