is this normal on my snail?
hiiii sooo this is Crao, our (my bf and me) snail we saved him and another one almost a year ago, the other one unfortunately didn't make it since his shell was way too broken to be saved even with all our efforts.
we we're just wondering if this white spot on the back of his shell is normal, it appeared in the couple last weeks, my boyfriend suppose that it is either a lack of calcium or an excess of calcium, he gives it some regularly.
we saw that other "outdoor" snails had some too so is this normal? we are parents chickens so please reassure us <3
(ps we have clean hands to not contaminate either crao or his food)
