It should get around 2 feet if not more, so definitely not for life in a 75. A 180 would be an absolute bare minimum in my opinion with bigger obviously being better.
75g is too small for a jar for life as others have said. The minimum tank size for a jar in my opinion is a 125g WIDE with a footprint of 72"L x 24"W x 17"H. The bigger the better if you can afford it money and space wise. Good luck.
