Not to long ago two of my tarantulas got a bald orange spot on their abdomen and it was deffinatly not a molt spot I have been keeping them fed with clean fresh water and keeping their cages clean and at the right temperature and humidity and I was wondering what could they possibly be, they are feeding just fine and seem to be doing ok but I am still worried about them considering I raised them from spiderlings, please help me on this any information will be appreciated thank you.
