I used to have a couple of tarantulas too....they are so fun to watch!
I had a particularly nice and large Peruvian Pink-Toe. I gave them to the entomology dept. at Cornell later on, since my daughter was going there for her degree in entomology.
By the way, in your photo- I see that's a coconut shell now, but at first I thought it was the abdomen of a much larger tarantula sitting off to the side.
When I was a kid I kept every type of insect and animal I could manage to capture....even ****roaches!

They were all cool to me.
Well, they'e not 'bugs', but I do keep worms as well. I have a special breed of composting worm in a bin in the house and they eat/process all our kitchen scraps and turn them into rich earthworm castings that I use in my vegetable garden. My worms ask for nothing in return, they are excellent 'livestock' to keep. I started with 2 lbs of worms (about 2000 worms), and now have probably about 5000 in the bin....though I wouldn't take the time to count them.
Here's a pile o' my little wormies:
