Blind Cave Fish

I don't know how many of you are at high school, but I am, and I despise my locker. It's too small, it's too dark, and it has no aesthetic appeal. I have tried keeping things in there, but plants tend to die, and mammals don't have enough room. Goldfish need light. Right now, I'm growing a bonsai potato (see link),which doesn't need light, but it's getting a little grotesque.

I think that little aquariums that fit into the top of a locker should be available, filled with blind cave fish. Fish are a preferable animal, because they don't require much intensive care, and they can easily last a weekend without food. Because they're blind, they won't care how much light there isn't. feed them every morning, and you've got a sustainable locker pet.
