Adding to an additional Pleco to a Tank?

[MagicGirl33]

I have a 32.5 gallon fluval flex tank with a built in filter and I have a clown pleco with a school of 10 neon tetras and a mystery snail. I wanted to add another pleco, specifically a bristlenose pleco, or any other pleco that works but I was wondering if that would work? I'm pretty sure they would get along, as my clown pleco is very timid and loves the other fish but is scared of us humans. I do want at least one fish that cleans the tank well as my clown pleco doesn't and I've never kept plecos together before. My water parameters are:
Ph: 7.2
Ammonia: 0
Nitrite: 0
Nitrate: 15
Hardness: 7 KH and 10 GH
Alkalinity: 8
So what are your thoughts?

I know most plecos are agressive with conspifics, so I would be very hesitant to add a 2nd pleco in that size tank.
