Hi bros

Please help me to ID this pleco

Panaque Nigrolineatus.

Agree, a little skinny P. nigrolineatus.

I don't think it's a , but a . The primary difference in the teeth and mouth is not apparent at this size, but there is a secondary feature that is visible. Panaque nigrolineatus have an oval shaped mouth, and Panaque cf. armbrusteri 'xingu' have a bell shaped mouth, which is also larger at similar body lengths to P. nigrolineatus.

I agree with Matthew....it's a panaque cf armbrusteri Rio Xingu

What's the difference on these and the L190? Thanks!

The teeth.

Not just the teeth,,,,also the colouration. The L190 is grey with black......yhe L027 goldish/yellow

For many years the L027 was rare....
