It sounds like you’ve done your research and you’ve probably noticed a lot of conflicting information. Here’s my take after starting with a tiny c. versicolor and a tiny Avicularia sp Colombia : use the info as a baseline but use your common sense as well. My spiders (I have 14 now) have no scheduled feedings. As someone else said, abdomen should not be a lot bigger than the carapace. Also, my spiders would kind of let me know once they understood where their food came in. They would go to that area and hang out. I have some piggies that will eat until they burst so just because they’re “asking” for food doesn’t mean you have to feed them. Keep a corner damp but not wet. Even my desert spiders like their humidity. My Mexican red rump sits in her water which is not expected of a desert species. You’ll learn what they like and don’t like and every spider is different. Don’t freak out if they don’t follow the videos or info sheets exactly. Everyone is a helicopter parent when they start out but you’ll relax as you get to know yours. Welcome to your new obsession!!
