I would doubt it. A 90 gal
tank stand is the same as a 75. I tried to put a 20 gal
tank under mine back in the day and the only way to do it was to go in from the side. I built my stand so I just removed the side panel and slipped it in. Standard door might be bigger but I doubt it. A 29 gal
is pretty tall too.
