Is it true an Iron nucleus requires the most amount of energy to hold it together?
Per nucleon, yes.

I would have thought it would be the larger the nucleus the more energy is required to hold it toghether.
The total binding energy increases with the nuclear mass, but the binding energy per nucleon hits a maximum at Fe.
