to awnser you granny, those are both tanganyikan cichlids with the first being an altolamprologus compressiceps. they are slow growers and are semiaggressive. the second is a frontasa burundi they tend to get somewhat big, and i dont think that you can put one in a tank under 75 gallons but i could be wrong. try googleing them. they are both very interesting fish and at some point or another i would like to keep some
