<some people have starved their fish to death in the hopes of controlling their water chemistry> I think to do this you would have to stop feeding completly and it still would take a very long time before they starved to death.I had a N.anomala that got under the ugf some how.I drained this tank except for enough water to cover the substrate and basicly forgot about it for 2 months.I finally got around to cleaning this tank and there he was,very pale but alive.With a little tlc he was back in shape in about 1 month.He never did get his beautiful colors back,but he did live for about another year.
