Full size adult discus are only a couple of inches shorter than the width of a 55g. They take a long time to reach that size but a 75 will be a better long term home. Most people think the 6-7" is full size but I have seen them much larger than that. I was honestly surprised the first time I saw a full size one.
+1 on a 75g. It's a much more versatile tank. Honestly I don't know why anyone gets a 55g when comparing it to a 75g standard.
