You ask how many. If otos, a group of 5-6 would work. Plants would be beneficial as Kym mentioned [they will clean algae off the glass, or any surface for that matter if they can get to it].
If BN pleco, as you have space, you could have more than 1. Males are territorial, but in a 125g there is space. You do need wood though, and it has to be real, not fake, as wood is a part of their essential diet. This holds for most pleco species. Also, they need a refuge spot, like being able to get under a chunk of wood or in a wood tunnel, and each pleco needs this sort of "home." And divide up the surface of the substrate with these chunks of wood so they can establish their individual territory around them.
Some pleco species can be quite a load on the tank, they produce a lot of waste. The larger ones mostly do this.
We have species profiles here, and the afore-mentioned fish are included. Second tab from the left in the blue bar across the top of the page, and they are under the Catfish section.
