NeoLamprologus multifasciatus is beautiful too.
Its fav shell is Neothauma tanganiycense also.
Same parameters.
If I remember well, no Chironomus plumosus aka Tipula annularis aka earthworm as they tend to poison fish living in hard and alkaline water like Tangafish.
You should prefer feed them with small crustaceans, insects, larvas, plankton of lake.
