Looks to be L75, but it's possible that it's L124,L301 or LDA002.....all pekolita sabaji
Beautiful fish! I house 4 L75's in my big tank. They get to about 10" and don't mind their own company at all. Looking to pick up 3 or 4 more to see if I can get them to breed. Probably my favorite loricariid.
Best of luck with yours. They eat everything offered once settled
