Ah, so now I need to be on the look out for an L114, and most likely an L011? Or just wait for the juvenile to grow up before making any judgements? The tank is a heavily planted 160g, so I'd think large enough for more than one set of plecos. (just nano fish, neos and a pair of SAE in the tank ...

Does this show what you need to see? (and thank you for any help you can provide, love this site)

The older fish (which is lighter in color and in the second photo) was sold as an L116. The darker, younger pleco (first photo) was also sold as an L116. I've never seen any odontodes on the older fish, and was wondering if they may eventually pair off, or if I have two, unrelated spotted plecos ...

I'm in the process of setting up a primarily invert tank, but wanted to have some fish in the tank to go with them. I picked up 24 pygmy corries the other day and added them to my 160G planted tank. If I notice any breeding behavior I'll be sure to post back here on what route seemed to do the trick.
