lungfish species

Hello.. I m from India.. Lungfish are pretty rare and uncommon here. I just purchased 2 lungfish from a renowned seller .. he said that both are of different species, but I don't think so. 1. West afriacn Lungfish 2. Marble lungfish I m posting photos of the same.. please tell me are they...

thinking about a lungfish for a 80gal but will be upgrading to larger 125-180 gallon in a few years. what lungfish stays the smallest and mellowest? thanks.
