Tanganicae get a beautiful blue sheen as adults, and grow over 15" long, so will require a long tank (min 6ft) with a sandy bottom and rocky areas to hide in to feel safe, hard water with a pH around 8 is perfect.
Mine grew very quickly in a 100 gallon + tank .
Their natural diet is algae, they are algae scrapers, so pellets like NLS Algaemax , or some other Spirolina/veggie base is best, and allowing a good crop of algae on the decor of the tank is a good idea.
Similar to the algae in this other Tilapine (Alcolapia alcalicus) tank below.
