I can't really tell. It doesn't appear to be getting thinner, but it still hides when it sees me. It is still alive, and I caught him/her today looking on the plate for food. So, I'm assuming she/he has realized the routine.
I'm now thinking of getting him/her a friend. I've pulled two of the mystery snails from the tank (so now two mystery snails, one ADF and however many evil little pond snails exist in that tank). It's a 10 g when I take the divider out (which I plan on doing). Should I QT a new ADF? It would be coming from the same tank at PetSmart as this one came from. I just don't really have anywhere to QT for 3 mos. So, if I have to QT I'll probably have to skip the friend. I will say the ADF and ACF are in tanks right next to each other (which I know is not ideal).
ETA: I should clarify, I don't have ACF, it's the ACF and ADF at PetSmart that are next to each other.
The mom of: Too many to list now.
