Opae ula shrimp, the lowest-maintenance pet on Earth. They are constantly going about their day's business, and they are social so they have small interactions with one another, or all hang out in one area and then all switch over to another area for seemingly no reason at all. You can keep a hundred in a gallon of water. They're spectacular. A whole society in miniature. Tip for opae ula: you will have your tank for a long time. Make it something you actually enjoy looking at. You can keep them in a deli container, but come on, a nice gallon bowl is not exactly gonna break the bank (especially since getting the shrimp shipped is going to run ~$50 for 20ish shrimp to start your colony). I keep mine in this bowl (https://www.amazon.com/dp/B08M5Q2DDS), plus a 4x8 inch oval wood dish as a lid, with some lava rock and a couple of sea urchin skeletons as hides that they don't seem to bother with yet (maybe they will once they're berried). It looks great and it's perfect on my desk, whenever I need a 15-second break from work I can just look over. Unlike a lot of inverts, you can have them even in a very buttoned-up corporate office environment, in a beautiful bowl, and they won't need fed when you're on PTO.
