The experince of Stefanie’s is very interesting since it refers to a new to me shrimp-species which is obviously able to tolerate the low pH and mineral content of Paro-waters.
Hitherto, we only know (by experience of Benjamin Wilden, Germany) that Caridinia parvidentata (which is rather small and without striking colours) is able to cope with that conditions. I can assert this; the propagation and breeding went very well.
With all the other shrimps sold in the aquarium trade (including the wild cherry) it was impossible to breed them successfully in the extreme Paro-waters. There are however shrimps occuring in high numbers in those waters. Obviously the trade was unable to import these species until now because they are not suited to the ordinary aquarium.
The friends who visit the Paro-habitats next should at any rate bring some of those shrimps home together with the fish they catch.
