well i went out a got an african knife, the lfs didnt have any bgk but the 2 african knifes they had were a really nice silver not the brown i expected, i ask can i keep 2 because they had the 2 africans in a small tank (maybe 20gallon max) and they were fine, but I still want a BGK but obviously not if there is going to be an issue with the 2 fish
