First of all, here is one of my five gallon tanks (both fives are hexes). This one is currently empty, patiently waiting for me to buy something to put in it. I'm not sure what yet...very possibly it will house yet another betta (I do adore the guys)...I'm just waiting to walk into the petstore and immediately fall in love with "the one." That's what happened with my VanGogh and I just adore him.
