I've got a 20 gal tank with 2 nerites and I used to have a Mystery Snail who died recently (it was about 7 months old but it also had a crack in the shell that developed maybe a month after I got it.). Today I noticed a crack in one of my nerites. It is still active and moving around like normal. My Ph is 8.2. Should I get some sort of calcium booster? Here are pictures of the cracked Nerite and the shell of the Mystery Snail.
