orange seam vs. gold nugget

[Dangerdoll]

ok, at the LFS, they had what appears to be gold nugget pleco's but listed as orange seam pleco's. To me, they don't really look that much the same to where the LFS would get the two confused, perhaps when they get older they do? Is there a major price difference of the two? From what I've read so far, the gold nugget gets to be 14+" but I haven't been able to find the size max of the orange seam. The cost of this so called "orange seam" was US$24.99........is that fair for either pleco?

Ok, what I was seeing was the "magnum orange seam", which looks nothing like the plain orange seam. Seeing these two (the orange seam and gold nugget) I can see they are very close look-wise, the orange seam's spots appear to me more plentiful and smaller. Can anyone tell me about the other differences between these two such as size differences? Personalities?
