FW: Trip to Central African Republic

My wife and I are leaving for the Central African Republic in 2 weeks and I'm interested in returning with some aquarium fish. I grew up over there and had an aquarium with some 4 or 5 different varieties of killifish - now that I'm attending school in CA I sort of miss it. My hope is to bring back a some fish and, as I've no experience in the area of importing or traveling with the things I need all the help I can get. I've a basic idea of how to physically transport them (one question is why no one uses a coleman cooler - why styrofoam?) and the concept of passing through US customs is fairly straight forward - but what about getting the fish out of C.A.R??? I don't want to end up in an African prison - and, as I am familiar with the workings of African immigration officials - I would like to have whatever forms, permits, documents and what-have-you so that I can somehow get out of there with my fish. Once again, any info on obstacles I could face would be very welcome - but especially; how do I find out about permits for CAR?

p.s. Like I said before, I had several varieties of killifish but no idea of their common names (I called 'em all "guppies") and now that I'm looking to import some, I will need not only common but scientific names for the Declaration forms. Any advice you can give here would be appreciated as well. Thanks
