Looks like a para pleco to me. I have one and he's about 7-8" and looks awesome. At first i thought he was some sort of leopard variation because of the spots then i finally found the L number after searching around.New PU. Took this pic within one minute after I let him out of the bag.
No one knew what this was when I got it including myself. ID anyone? Peckoltia sp? He's about 4.5 inches.
