4. I caught a freshwater crab today. Can you tell me how to keep it and what it eats?

Crabs are omnivorous and can eat anything, including bread crumbs and rice scraps. If you keep them in a fish tank, the following two points are very important: 1. Give them a place to hide underwater 2. There must be an island above the water surface for them to climb up. Just change the water every few days. The optimal water temperature is 25-30 degrees. Send me a picture or something and I'll help you see if it works.
