someone can correct me if im wrong but IMO
every tank needs a heater, filtration and lights. for a 30 gallon tank i would recomend a 100w or 150w heater. in the summer i dont use a heater because i set my Air conditioner at 78* and my tank water stays at that temperature but if the air ever gets colder in your place of residence a heater is necessary to keep the temperature where you want it.
things i would recommend researching would be what fish you are planing on stocking in your tank.
things we can help with once you decide on what fish your children like are compatibility of fish, photo period of your lighting, how many fish you can keep,
if you have questions ask and we will be glad to help you out
one thing i would like to make sure you know is when you are finally able to get fish, the ones in the store are not full grown, if you are not planning on getting a larger tank when they do grow make sure you research how big they will get otherwise they will quickly run out of room and not lead very happy lives
