my new snail (the magenta if you looked at my other post) has not come out of his shell yet he will sort of peak his tiny eyes out of the shell but he hasnt actually come out should i give it some time since i got him only 3-4 days ago? he is really cute the only reason i am worried is b/c the other 3 snails are all out and climbing around. thanks

Something could have him/her stressed. Have you tested the water? Is the tank cycled? Are there any fish in the tank? What kind of substrate are you using?
