so when i first got my mandarin i didnt notice anything unsymmetrical and then i remember once day soon after seeing a blue dark blue dot on his cheek.. which has been there since and i thought i just spaced out for a while haha... but now there is a blue dot on his nose that definitely wasnt there before... any fungus or disease or deficiency you can think of that he might have?
 
yea ive never heard of anything remotely like this... hens why im asking haha
maybe hes just changing colour slowly as he gets older...
