I can not speak for anyone except myself but my comment was based off of my views having changed since the beginning to that of pity towards the fish in this world forced to live in mere puddles when compared to their size.your pond is a square 52”x52” by 20” tall. Solid Foot print for several Floida Gar. The comments on them being not flexible and your tank to small I suspect have the 20” as a width not the height. No issues with them turning in that size. Is bigger better? Of course My thoughts
