I have 2 Mystery Snails and a betta in a 3.5G tank. Tank is filtered and has a heater. One snail has not grown at all while the other has nearly doubled in size. He is lathargic and I rarely see him eat his food or even come out of the shell. His shell has turned to a dull dark brown colour and looks to be cracking a little bit. Does this sound like a water issue? Does he sound sick? What can I do to help him. In the last picture, he is the smaller snail in the front.
