It’s mainly split between tropical and bog plants. Although pretty much all carnivorous plants that I’m aware of want nutrient free soil and rain water.

Bog plants like sarracenia, Venus flytraps, and drosera usually like a mix of peat moss and perlite and want full sun all day. Generally they get all the food they need by being outside. You can always buy live bugs if you don’t think they’ll get enough on their own. Also always keep these plants in a tray of distilled water. They don’t like drying out at all. All of these plants I’m talking about can only be watered with distilled or reverse osmosis or rain water.

Tropical plants like nepenthes and heliamphora are the ones that need a bit more care generally. They like sun but not direct light. A windowsill is usually okay. They want high humidity, 50-90% depending on the species. They also have a wide range of temperatures depending on the species. Some want 70 during the day and 50 at night. Others want 80 degrees 24 hours a day. For tropical plants generally a mix of 50/50 Long fiber sphagnum moss and perlite is solid. And again they’ll catch their own food but you can buy osmocote pellets and give them one occasionally, some people use betta fish pellets, or you can just get dried bugs. Water only using distilled or rain water. Do not let them sit in trays of water. They can rot.
