Snails and low salinity

[Earthgoddess]

I was wondering how low of salinity snails can handle since all of my snails in our quarantine tank and the babies all died I had the salinity lowered to 1.009 for sick fish so how low can the snails handle so I know next time when I need to take them out? Also I wonder about hermit crabs how low can they handle and for how long?

if the snails and crabs can handle the lower salinity then so can the parasites that are making your fish sick. in short the snails and crabs must be removed for the treatment to be effective. if you wantto keep them

Unfortunately, invertebrates cannot handle hyposaline conditions. Their internal osmotic concentrations are the same as the surrounding water (marine fish have a lower concentration than that of NSW), so when in hyposaline conditions, they suffer from osmotic shock.
