Well, I wish I knew what minerals I was talking about - then I'd be more 
specific.
But that reminds me: at the auction there was a bottle of "South American 
Cichlid
Salts" that people thought sounded amusing, and so since few bid on it I got it 
for $2.
It is actually a nice blend of salts (mineral), including calcium, potassium,
magnesium, and ... I can't find the bottle now .... a bunch of other standard 
minerals
that are needed for most life forms. So I think I might use that for shrimp and 
things.

I read a scientific paper the other day saying that depletion of calcium in 
some lakes
has caused a decline in the anount of zooplankton for fish to feed on. Daphnia 
was the
principle organism they studied and that's why i read it. But the lesson was 
that
Daphnia require a minimum amount of calcium in their water or they die off 
gradually.
So maybe that wouls be true for other freshwater shrimp. Additionally they 
probably
have a minimum requirement for some of the other minerals, like magnesium and
phosphorous.

Susan Welenofsky has mentioned before that the Cherry Shrimp do better when she 
adds
minerals, and I think she was using a little Marine Salt - a nice blend of 
common and
uncommon mineral salts including lots of calcium and magnesium.She also adds 
iodine
supplements in some cases.
