Mystery Snail Death Question
I searched for answers but was unable to find, I apologize if this was answered elsewhere already.
Today, as I was performing a water change with my daughter for her betta, Swimmy, and mystery snail, Squishy On The Inside Esq. II, it became clear to me that Squishy was dead. Her foot fell off when I tried to pull her out of the tank to have a look at her. This... is not the part I need help with, as that is one dead snail.
What bewilders me is that I thought I understood how to detect a dead snail, and she was very, VERY dead today. She stopped moving for many days, but I read stories about snails not moving for long periods of time and still being alive. So, I have been testing ammonia in the water maybe every other day for a couple weeks, and sniffing the snail periodically, and somehow I seem to have missed the moment of death by a lot. I'm worried about what Swimmy was exposed to, and how that will affect his life span, so I'd like to get a better handle on this before we get another snail. (Actually, my daughter really wants to have two of them. They're neat critters, I don't blame her.)
Can anyone advise on detecting snail death in future?
