anyone have a picture of adult rainbow sharks? or red tailed?

[bobsaget]

ive never seen an adult sized rainbow or RT shark. ive seen them top out at about 2.5 inches..but i know they can get to 6. does anyone have a pic? hopefully, a picture where i can kind of compare the size (meaning its not just a pic of the shark in a tank, up close, with no way to tell how big it actually is)

I searched a little for you. This one doesn't have a reference point, but it's pretty thick, making me believe it's pretty long. (Fish generally grow long, then thick.)
