which gold nugget are you?

still not having managed to get a decent photo of the new little gold nugget pleco, i have been doing some research on planetcatfish and have come across this article concerning the identification of the species.

there are, it seems three distinct species of gold nugget, all originating from different points along river iriri in rio (L085 being the adult form of L018). after reading the article and the descriptions of each type i am fairly confident that i have bought species L081, not L177 as was stated in the shop. i knew L177 would not grow larger than 20cm which is why i wanted it, aside from the fish being really pretty to look at. however, if it is L081 then this is fine also as this species shouldn't exceed more than 18cm. i hope it is not the other remaining species, L018/L085 as this one could grow up to 35cm! and that is too big! i will certainly be informing the shop keeper of his error, especially since he was a bit of a smart-arse. i imagine the price for each fish is the same (i paid £25 for a 5cm specimen!) as they all come from the same place, but thats not the point.
