i was holding my ball python tonight and suddenly i saw a round black dot walking on my hand, i don't know if it was a mite but it looks like every describes them altough i dont know the actual size of it but it was small like double the size of a fullstop. when i got the snake i washed t he new container with antiseptic as usual to kill micro organsm like bacteria and such wich i do every month to my other snake too. i never saw anything like this on the snake in the whole 3days it has been here neither in the viv, i check the snake well and there was nothing on him :S should i be alarmed?
