Nice bowfront.. IMO, i don't see why you'd get a 30g it's just 4 more gallons than what you have. You should go with something a little different like a nice high tech rimless tank like those Mr. Aqua 12-Long or something.. I actually just started the same 26g bow front.. I'm gonna start a tank journal thread here on it but i already got one going in the AA forums for now... Check it out..
