I also have 3 BPs, as does my husband. Although BPs are very slow growing, they can and do reach dinner plate size. If you intend to keep them, you really need to consider upgrading your tank to a minimum of 75 gallons. At that point, I can see you keeping perhaps a schooling species with them, but not in a 55. BPs will and do (I've unfortunately witnessed it) eat any fish that fits into their mouths. You need to be careful to not purchase too small of a schooling species.
