I saw what the store owner described to me as an African Lake (Malawi I
think) Lobster in a LFS. About 3 inches long. I'm thinking of picking it up
and adding it to my 55 gal with my two other exiting fish (Frontosa - Hand
sized 3 years old and Yellow Lab - 4 inch 5 years old). Store owner says
they require no special care. That they eat normal cichlid food and don't
really interact with existing fish.

Well... is all that true? Anyone have any advice on this?
