There has been no real evolution of the fish bowl. The design has always been round, usually with an open portal, throw in some fish, gravel and a centerpiece, that's about it. Well maybe it's time to update the fish bowl's design with something soon to be vintage, the incandescent light bulb.
Check out these fun fish bowl designs that mimic the now banned from production, incandescent light bulb. In what is sure to drum up conversation at your next house party, these unique concepts can work as accent pieces or even centerpieces. FYI, the addition of a filter system might be a good idea.
