Bristlenose or Common Pleco?

I'm hoping someone here can put my mind to rest... I was told by the guy at my petstore that this little guy was a Bristlenose Pleco when I bought him (or her?)

I came face to face with a massive Common Pleco today and started to get a bit nervous at the sheer size of it. I'm new to keeping fish and I'm finding it difficult to tell them apart. I can't see any bristles on my fish, but maybe thats because of how young it it? (About an inch long.) or maybe because this fish is female?

I'm just a bit worried that I might have a baby Common Pleco on my hands.






These are the best pictures I could get of him. He's very quick and spends most of the time hiding...

Any input would be helpful! Thank you!

I don't think it looks like a common pleco, but it is small, and fish often look different when they are grown up - especially patterned fish. There are a lot of bristle nose pleco species. Catfish Common Names Beginning with B

125 - BGK, chanchito cichlid, pictus cats, silver dollars, palmas bichir
125 - cichlids (severums, bolivian rams, chocolate), rainbows ( turquoise, red), loaches (angelicus, zebra, kuhli and horseface), plecos (BN, RL and clown), denison barbs, tiretrack eel, pearl gouramis, betta
90 - Congo tetras, african knife, upside down cats, spotted ctenopoma, kribensis, delhezzi bichir
2.5 - betta

I counted the spines on the back of its dorsal fin too. Looks like it's got 7 or 8. I read Common Plecos will have about 13?

The biggest tank I've got is 40 gallons, which is my real concern. I'm not prepared to have a foot long fish on my hands so I'm really hoping the guy at the petstore was right. (My Pleco was in a tank labeled Bristlenose, but all the ones except for the one I got were Albino Bristlenose.)

You might find some help in our profile of the Bristlenose; if a BN it will be in the Ancistrus genus and these are fairly easy to identify as it explains:

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
