Hi everyone I just got a bamboo shark hatch and hatched it yesterday and is in a breeder box in my 40 gallon(don’t worry I have a 200 gallon) and I was reading that they need iodine or they get a goiter. I own my own fishing business in Tampa area The WaterSide Fishing pls support. And I catch half an inch mullet and saltwater glass shrimp- do those contain iodine for my shark
