Gotta say brother, I'm not sure this is a great idea. Tanks are generally noisy and bright, which may be nice sometimes (ie playtime) but terrible other times (ie naptime, bedtime, time you will cherish as a new parent). Take it from someone with a 2-year old now, I think this might not turn out well. :/ Don't mean to be an internet-parent, just trying to help guide you through the minefield of parenting from a fellow aquarist perspective. Good luck!
