I think that was in reference to the bozo that said to dump the bicher. It's a matter of taste, but since there are only a couple types of fish I that would even consider giving up my bichers for(with one a fairly close relative and the other illegal in the US of A), I would tend to agree.
While Silver Dollars may be pretty, they don't even come close to the awesomeness of polypterids.(Is that right or did I just make up a word?)
