I grew up having a large tank with an oscar and JD's and other fish. So it just seems normal to me to have a tank. But I am much more "obsessed" then my parents ever were with their tank, I do a lot more research about the fish I am wanting. But what keeps me with the larger fish is their personalities. You can have the prettiest guppy or whatever other fish but they just don't have the same personality as my Africans and S. Americans. Even my african lace catfish has a crazy personality. I feel people end up thinking I am crazy because I will talk about my fish like they are my cat or dog. I do have my cats and dog and I love them more than anything, but it's safe to say I have become just as attached to my fish.
