well raptors, i am slowly becoming a fan of the
betta, i am sure he would love a 5gallon tank to call his own!!! if you put the right stuff (decorations and plants) it would look stunning. they are amazingly curious fish with a great personality too! and best of all you would be saving one from the jar(no doubt) that he currently lives in at the
LFS.
a 5 gallon really limits you on what you would put in there. this is however just a idea many more ideas will flow soon from other members
