since reading this i've noticed both of mine have the blotches. one has the larger barbels you can see in the pic. the other has very tiny ones a bit lower... i am the only one that can see them due to my eyes are both better than 20/20, so i'd dare to say most would consider that needing magnification. the funny part, i have seen one atleast eat bba... not sure about both now. the larger of the 2 has a favorite perch where it seems he loves to snack on java moss periodicallly. the smaller one has never touched it at all. i'd dare to say the little guy is a langei and the larger one that seems to have a more yellow tint to his fins is probably an atrilimes. as far as i see they both fit the descriptions, pics and traits of said species stated above. the only thing i can't figure out is that they both have the spots about the anal area. funky... i'm wondering what else there is to find out in the future. i thought for sure this was not possible at one time as i was sure i had read all there was to know and i'd struck gold when i saw the "real ones" for sale. my how things have changed in such a short time. a very interesting read... and a second thought once again about the elusive "true sae"... thank you.
