Hello. I am the owner of a Lepomis cyanellus (green sunfish), 2 Polypterus senegalus (Senegal bichirs), and a Lepidosiren paradoxa (South American lungfish). The sunfish came with a batch of fat head minnows that I bought to feed my bichirs and is now approaching 4". My lungfish I got back in 1999 and is what first got me interested in primitive fish. I found this site while searching for information about lungfish.
