You guys are welcome.
Please note the mistake I made above where I used L34. I meant to refer to L134, aka Leopard Frog Pleco which is correctly named as Peckoltia compta.
As the L-Numbered Loricariidae are formally described the use of the L-number should be discontinued.
DATZ came up with the it as an interim solution for identifying the flood of not yet scientifically described Loricariidae species to reduce confusion.
