I think we should not be too hard on the guy, I think most of us have been at this stage in the hobby at some point. I know I have been there, just wanting so bad to find a way to keep all the cool fish you find.
So my message to the original poster is sorry about my fellow fishkeepers being a little harsh, but also keep in mind that the answers they gave are true and correct, they have experience and know what they are talking about and are just trying to help you be your best at fishkeeping.
Btw in my opinion (take note: opinion) a 450 liter tank is worth a try with the bgk (at least a few years), ropefish and a bichir (maye just not some of the largest types). But I would recommend to not do the common pleco.
