Mouth rot please help
 

Hello I have someone who is selling a blue tongue. He said that the skink has mild mouth rot and has been to the vet. He said he would send the About silver Sulfadiazine cream.

I wanted to know if it’s worth it to purchase this skink or wait until a better one comes along?

There is no good reason to purchase an animal that is known to be ill. In my opinion, it's not responsible to sell a sick animal. Save yourself the hassle and wait for a healthy animal. Blue-tongues are not super rare.
