New Nerite Snails!

This is my second order of Nerite snails! The first order, only ONE moved out of 7 and 2 days later, was laying on the bottom of my tank hanging out of its shell. All of them had a horrible smell, so I knew they were DOA especially after not moving for the 48hrs in my tank. I got another 7 in the mail and they were pretty beat up during transport to say the least (traveled from CA to VA, if these don’t survive I’m definitely trying to find someone more local). First 2 pics are when I opened them from transport at 1pm, they acclimated to my tank and were dropped in around 2pm on 1/3. The next pic is them after my tank water change at 10pm the same day. Next pic is from today (1/4) at 7pm. None have loved, but one is slightly raised up? He wasn’t moving at all though (last pic). The pamphlet said give them 24-48hrs to notice movement, but I have a feeling these aren’t going to survive again 🥲 rank parameters are normal - temp ranges from 72-74°F, ammonia 0ppm, nitrites 0ppm, nitrates 5ppm (checked yesterday and today, same results). Am I being paranoid or is this normal behavior for them? And any people on the east coast that sell nerites & apple/mystery snails?? lol my 36gal tank currently has ramshorns and 2 fancy goldfish. THANK YOUUUU
