For a 75gallon go with a male jaguar. They would normally grow around 14"-16" in home aquariums and to me 75gallon is good enough as long as water changes is keep up.
I have a male 13" jaguar in a divided 125gallon and he seems ok. I do 80% water change every week.
If you like jaguar go get one and a 75gallon is a pretty good size tank considering most if not all fish form a pet store will end up being bought by a kid and his 10gallon tank.
Another think once the jaguar hit 12" its growth slows down drastically.
