Mystery snail with shell cracks
so i bought this snail from the pet shop about 2 months ago. When i bought him his shell was already cracked and frayed, but he was the heaviest looking snail there so i thought he would be fine. but ever since i got him his shell has become progressively worse. however he is still very healthy and active and a good eater. so what can i do to help his shell.
p.s i have tried to feed his brittle bone but he wasn't interested at all.
