How many smaller plecos in a 29g?

[new2betas]

I am now looking at a small school of the smaller variety of plecos I have been looking at. How many could I put in my 29g if I have two other smaller schools of fish (two schools of possibly 6 each). I am looking at red fin dwarf plecos, chocolate zebra plecos, and bulldog plecos. Does anyone have experience with any of these plecos? How many could I have in my 29g tank?

I'm not sure what a "red fin dwarf pleco" is but I wouldn't put more than 3 total of either the chocolate zebra or bulldog plecos. More might work but I wouldn't chance it as they might tear up the tank while disputing over territory. Personally I'd go with 2 BN plecos (ancistrus).
