I'm not 100% sure that these fish are L264.
The dots are small, the dots stop at the edge of the dorsal fin.
Also is the colour seems different.
I noticed L263 grows much bigger, my tank isn't big enough for L263

The pleco's are between 10 and 13 cm.
I was comparing with the last three pictures, these fish are from a keeper in Germany.







All of these L264 do have dots in the edge of the dorsal fin
