Oh don't I wish! I saw these for sale about five years ago at R15 
EACH (That's a sixpack of beer at today's prices. Probably two 
sixpacks at the prices of the time) I haven't seen them since either. 
I know there is an indigenous species, Caridina nilotica. Someone 
from the Institute for Water Research offered to collect some for me 
in KwaZulu-Natal since they don't occur this far South. 

Anyway I bleached the plants yesterday. Can't say I've seen any
