Here's some things I think you can do:

  1. Order an air pump. I saw someone in another thread linked to one on DX.com, that's fine, but delivery can be like a month+. You can also look for a USB air pump, there is one on amazon if you need it.
  2. Order a USB battery pack. If you want to do the least work possible get one with two outputs, otherwise any one will be fine.
  3. solder the wires to the battery adaptor

    Once you have that done, reply to this message and I'll see if I can help you further.

I am working a similar problem to activate a pump to fill a tank. Two aquarium float switches and a relay should do it.

Here's the thread I started; a lot of the comments are relevant to you. I'm still wrapping my brain around relays so someone else will have to help you for that.

A little pond pump like this would probably do the job.
