Will My Plecos Fight?

[Pl*co]

After I get my 65g set up and after my new pleco finishes quarantine i want to put both my plecos in the tank. It'll have tons of decoration (driftwood, rock, fake plants, and i'm going to plant live plants too). One is about 4 inches long, the other about 6-7 and they might both be the same species. Not sure yet, I'll post pics later though. Will they likely fight?

depends on the type, what does they look like? certain plecs really do not like each other, like the gold nugget.

One is a Pterygoplichthys pardalis and the other is a Pterygoplichthys gibbiceps (I think)

a lot of people know more than me on here, so hopefully some more weigh in, but both of those guys get 16+ inches and that might be a problem as they get older and want to enlarge their territories. I have heard the gibbiceps can become territorial but I have not kept either.

Yeah, when they get larger I'll have to get them a bigger tank of course. Right now they're very small, so it shouldn't be a problem. I just hope they don't fight the second I put them both in the tank..
