I am not going to belabour this, as I have made the case and can't force you or anyone to agree with fact if you don't want to. Your comment that your fish "shows no sign of stress" is frankly indicative that you have no knowledge of this fish. The behaviour it is displaying in that video is extreme stress
. It is cruel to keep the fish in such conditions. It may "survive" somehow, it may contract disease, it will
have internal problems, and most likely die prematurely. If you don't care about this, so be it.
