I was just thinking about how often Americans talk about buying a little common pleco and ending up with a big poo machine. Here in Finland commons are pretty rare and usually have to be ordered separately. BNs are much more common, to the extent of being troublesome thanks to their profilic breeding habits. I've also wondered why Finland has a relatively informed and almost too nitpicky scene compared to many other countries. For example, on one Finnish aquarium group, if you write about your goldfish, you'll get bashed right away if they aren't in at least 250 gallons and in groups of at least 6 fish.
