Ancistrus is a genus of freshwater fish in the family Loricariidae of order Siluriformes. Fish of this genus are commonly known as the bushynose or bristlenose plecos.
there are at least a dozen or more species of bushynose type plecos....almost 600 known species of loricaridae...
i would believe that the 2 you got are the same species..
keep in mind joey that only the males will get bristles of any size...and those will be on the snout and almost up to the eyes....females may get very small bristle ; but only around the front edge of the snout...
