Brazilian long fin (?) common pleco

[Pedraz]

Hi Everybody, I'm always reading planetcatfish, but never had to post or sign before, but I need a help!
I can't ID my pleco. I was bought in a normal store, bought as a pleco for 1$ more or less, I'm from Brazil and the fish came from Barcelos area certain.
I'm thinking about Hypstomus, but a friend o mine told about ancistrus, I look up a lot os species and think they just don't match. The strange, is that the fish, apparent, has a long fin.
So, here the pictures, I hope you all try to help a brazilian friend.
I will try to post some better pics, but my cel cam is a garbage
Regards

This is a species of

Pterygoplichthys

, not quite sure which one. Looks closest to P. pardalis.

[Acanthicus]

Interesting specimen, as Jools said a Pterygoplichthys or Liposarcus if you want it a little more detailed. Before reading the origin I thought about P. ambrosettii, since I collected similar looking specimens in Bolivia. But knowing the origin now, it's more likely pardalis or disjunctivus.

cheers, Daniel

Thanks guys, this genus was my third option. I'd thought cause of the fin, but never ever ever think it was a pardalis (here is call pineapple pleco, cascudo abacaxi).
All Pterygoplichthys got this type of V fin?

I am not sure what you mean by v-fin? Pterygoplichthys are most readily identified because of the larger number of soft dorsal fin rays.

About a year ago, I saw some long finned common plecos. The fins were like that of a long finned bristlenose. I had pictures of it, I will have to look on Facebook when I am on a computer.
