Should i be worried about it??It could be a leaky joint from a injury (hemolymph). If its water it beads up on tarantulas...they are waterproof. That's why they can walk on water like Jesus.
Could you explain how i should apply corn starch and also should i not feed her for while??If it's a injury and it keeps bleeding you can put flour or corn starch on the area to stop the bleeding. I'm sure it will be fine if that's what it is. I dont see droplets anywhere else to suggest it is water.
Applied some corn starch on the spot i hope she heals really soonNo reason why she shouldn't eat. Just feed her as normal. The corn starch just put it in a spoon and dump a little on the spot. If it's not bleeding anymore I wouldnt worry about it. It's not a life threatening bleed if that is all it is.
