I'm a bit of a fish geek as you can tell from my hubs. I own a guinea pig, four hermit crabs, three African dwarf frogs, and a betta fish.
I am a big believer in researching your pets before you buy them, not after you realize you don't even know what they eat! This is an almost surefire way to for a fish to go belly-up. Other pets also require research before you get them, too, to see if you want to care for them for their whole lives.
If you're reading my hubs, you're probably looking into buying some pet of some kind, because the main topic I write about is on pets and animals. Hope you find what you're looking for!
