this is a update on my snail,
well i contacted the former owner who told me they were 6 ,3 and 2, he offered to come and look at the snail iv been having problems with which was nice of him,,, when he arrived he picked up (mika as my children called him) and straight away he said he was dead, he thinks it was just old age or because he layed eggs the day before i had him and that can sometimes happen (iv never heard this)
the sad thing is i think the other snails knew he had gone as they have not been any where near him.
im so upset that my first experiance of owning snails has been such a sad 1, but saying that its been a good lesson in learning how to care for them properly as done so much looking up on the net.
well thanks to all of you for the advice im very greatfull
