hi my peacock which i have only had for a few weeks has shell disease...white turning brown=( i knew when i purchased him he had the disease but thought through lots of feeding ,good water quality, low lighting, and iodine for his molting would nurse him back to better health after a few molts. however i found out just recently under closer examination that he also has a parasitic crustacean or snail/ under his pleopods? I heard they can prevent them from molting...which would doom them to the shell disease/ if there's anything i can do please help me with any suggestions...thanks
