Well, my mind was made up for me, I think... Found a gorgeous short finned iridescent white male betta today. He's going in my qt 1.5 gal for now and he'll be the centerpiece of my 20 gal in a couple weeks once I get it fresh again. Thankfully my cycle should be short since I have a fresh tank to seed the filter. Either that or he'll get my 5 gallon to himself after I move my cray to the 20 gallon.
