Pet jumping spider.
Honestly 10 star pet. They eat a small bug every other day or so. They look adorable. They will recognize and react to you, and you can even train them to accept handling. They come in a wide variety of colors.
Downsides are that you'll probably end up getting more than one (do NOT co-hab them!), or that they only live for 1-3 years. If you enjoy having the spider though, you can look into other arthropods like tarantulas, or vinegaroons (which look scary, but are harmless and have very sweet dispositions).
