Ancistrus

This one is probably very difficult, some Ancistrus without location. It was listed as A. tamboensis, but that doesn't seems to fit.

I'd go for

Ancistrus sp`rio_paraguay`

. It's a young fish too, so still some development to come.

Thanks! That was the same answer I found, but I was doubting because Ancistrus sp. `RIO TOCANTINS` seems to look rather close as well. Is there any way you could tell why this one is less likely to fit?
