I have this red tail boa for 2 months now, when i was buying her i was told she is 2 years, when i got her home i realised after few days she has mites, after some fighting i got rid of the rather quickly, shes mite free now but today i noticed two scales on her body that seem to stick out and look bad. Is this first signs of scale rot ?? I will also add other pictures of her body that look like scars or previous infections ?
