no not actual blood as in sticky stuff .....

but a pic of my male Hercules a couple of days before he is due to shed

As you can see its big enough he cant tip it , and he sometimes likes to sit in there for a few hours at a time before he is due to shed which is good cause it is hell trying to work on a Blood with a bad shed ..lol

I will post some more pics soon after he has shed. That water box is about 20 Inches long to give you an idea of size he currently is.
