I beg to differ.
I place my tank to the right of my door.
No issues at all.
You should consider the overall design and ergonomics aspects as a whole so that the tank proves to be not only a eye candy but also an area that allows you to do access or maintanence with ease.
Of course, it applies to me cos FS is something that is zero as it is not in line with my faith.
So end of the day, it's up to you but it works fantastic for me ya.
All the best, your floor plan shows a very good layout out.
No odd corners.
2050 area looks good to me too but I will also consider the area 90 degree clockwise to 2050 as i do not enjoy it when the side of the tank forms part of the entrance way to the rooms.
Just my personal preference.
Enjoy your planning ... fantastic home layout.
