Nass vibex snails dead

[milomlo]

All other snails, shrimps, crabs fine but every single Nass vibex snail is dead. Some stool have their foot sticking out and their antenna. They are just dead, like they were crawling then nothing. What would cause this?

Anyone??

Not sure. I had some snails do the same thing. I posted a while back about it and didnt get any response either. I thought they were hardy.

A small spike in parameters maybe, but even if that was the case you wouldnt find evidence of it now other that nitrates.
