crypto?

[bob_thesnowman]

hey,i recently(less then an hour ago)had my leopard gecko die on me....maybe i'm just paranoid now,i dunno...but could anyone tell me physical signs of crypto,i remember reading something in a forum about a leopard with a black spot,and it had crypto,one of my other leo's who was in the same tank,has a blue spot on his stomache,he seems to be fine though,his tail is a good size for his age,should i be worried?
