Hi, thanks for your reply. I don't think it is Pterygoplichthys joselimaianus (L 1/L22), it was in a tank with L-001s and it looks completely different. P. joselimaianus has the gold spots and flecks all over there body and an even colouring, this fish doesn't and has an almost camouflage pattern of light and dark exactly like L313 Pterygoplichys spec. as shown in Aqualog L-numbers book.
