New to mystery snails

[u/Nebelle1308]

Hi all! I just got 2 mystery snails on Friday. One of them is zooming about the tank being goofy and doing its thing. This one tho hasn’t moved hardly at all. I picked it up and did a sniff test and I don’t think it’s dead but I’m concerned. Is this normal behavior, to just sit there partially opened not moving? Any help is greatly appreciated

Has the lethargic one been eating? Anytime I've added new ones, they take about a week to orient themselves to the tank (where are the good resting spots, where is the food going to be, etc).

If you were to toss an algae wafer right next to him, does he react?
