I'm looking to uprade my aquarium to something larger. I'm currently using a 56 gallon that is about 30" wide. I'm kinda limited on space and want to do at least a 150 ( want to do a few tangs) my question is I see many 50" wide 150s and was wondering if wide is better? I could fit a 6' but it would be tight. I don't want to regret getting something to narrow. How much better is a wider tank thanks
