Guppy care ain't that hard... For there's not that much to it...
You can keep them at room temperature (so, a heater is not needed). They eat almost everything you offer. Short finned guppies can be kept in moderate soft water till hard. And large finned guppies can be kept in harder water. In softer water the fins of those large finned guppies get torn.
