"Common" names are next to useless as they can be at the whim of the store, the supplier, whatever. I know of local stores that give "interesting" names to the fish in their tanks, but names that have absolutely no relevance to the fish and you can never find the fish online because the store simply makes up the name to sell the fish.
However, a "common Ancistrus" should be the fish in our profile under Bristlenose Catfish. As noted in the profile, there are currently some 65 species in the genus Ancistrus, and the exact species of the "common" BN is not known, which is why I entered the fish as "Ancistrus sp" ["sp" = species]. The profile info applies to this fish. Other species in the genus may be more demanding in terms of water parameters. All Ancistrus species have the "bristles" on the head.
I agree with Angel, don't buy a fish to eat algae unless you really like and want that particular fish. And if you do, then ensure you have algae when you acquire it so it will adjust better. Most "algae" eating fish will learn to feed from prepared sinking foods, veggies, etc., but at first they will be more likely to settle down if they have their natural food available, algae.
