Pleco Tank Question!?!?

ok so I have a weird shape tank, it's sort of like 2 hexagon tanks that are 45cm straight across connected by two 20cm tubes that are 3 inches diameter.now knowing the size of my tank do you think that two bristlenose plecos (1 normal and 1 albino) would be ok if i put 1 piece of driftwood in each side because I've heard that plecos like to eat driftwood and I was thinking that 2 pieces would mean that their would be 1 pleco on each side of my tank meaning that they would not be territorial. also there are a few neon tetras and a few zebra danios if that makes any difference
