Is there such thing as a 30 gallon bow front?

[mjc041800]

I got my tank off of Craigslist and the guy said it was a 30 bow front. Every time I look up stuff online I never really see anything about a 30 gallon one. My dimensions, in inches, are 30Lx15Wx20H and the width is at the farthest/largest point or area of the bow front. I saw online that a 36 gallon's dimensions are 30Lx15Wx21H. Is mine probably a 36 gallon?

This is my 36 gallon bow next to a 55. If it looks like that that's probably what it is
