Hi Tom, this is the first time I write to this list. But I'll try it. TOM PRICE wrote: > > ...

The current name is melanochromis auratus. >...I also don't have any Malawi lake salts You don't need any "Malawi lake salts" as far as I know. I have Malawi cichlids since 20 years, and I never had problems. The water in my tanks was pH 7.5 ... 8, dGH 15, temperature 25 ... 28 ° C ! > > Does anyone know exactly what's in the Malawi lake salts?

You should control the hardness and the pH, and when the water ist not enough basic or hard put normally chalk into your back filter. Chalk is cheaper than crushed corals, and it does the same. good luck Wilfred Teiser phoenix1@t-online.de
