Common Or Sailfin? (L021 Or L083)?

[pkppv]

I have a pleco, and im not quite sure what he is. He was labeled as common, but he looked much different than the others in the store display. After doing some research i think he may be a sailfin.

Are there any distinguishing characteristics between the two?

If worst comes to worst ill upload a photo to help you guys, but i figure there must be a way for me to differentiate him on my own.

If you know what both look like they are easy to tell apart but it is hard to put into words, the dorsal and pattern are subtly different.

A picture would solve it as mentioned above, in the meantime look at both these links to see if you can decide for yourself.

Low quality...I know... But this is all I've got for a camera. I think it's sailfin looking at the pectoral, caudal, and dorsal fin patterns

Not the easiest photo to tell but if I were a betting man I would say common
