| Re: Banded catshark has a goiter?? Welcome to the forum blownz281!
In the March 2007 edition of the FAMA Freshwater and Marine Aquarium magazine there is an article entitled "5 Keeper Sharks!" which details goiter problems, among others, with sharks that are small enough to keep in a home aquarium. The first point that is brought up is that even though these are small sharks, THEY NEED A LARGE TANK!!! And for the record, they do mention the banded bamboo shark, which I assume is the same as your banded 'catshark'.
So, obviously ANY fish needs adequate space and gallonage to thrive (which is always our true intention...right?) so this might be the root of your problems here since having less than an ideal situation would open your fish up to stress and hence, more illnesses and issues. The SMALLEST recomended tank size is a very robust 500 gallon tank; meaning one that is wide, long, and semi-tall in nature (versus one that is very tall, long, and skinny, for example).
You should also have a very fine substrate according to this article because most of these 'keeper sharks' like to nose around in the substrate, and some of them do more 'walking' than swimming so a rougher substrate can cause scratches or injuries which would then be susceptible to infection....which could possibly appear to be goiter to anyone.
More to the point, again, according to the article, goiter is caused by a lack of iodine (as with humans as well, I believe) and so you can reverse this situation by doing BOTH; supplimenting with iodine in the water and possibly in the food (such as 'gut packing' the shrimp your fish eats) AND reducing the amount of nitrates that have accumulated in the tank at any given time. From what I read and understand from reading this article, reducing nitrates is going to be as important as supplimenting iodine so it sounds like you cannot really skimp on one aspect and still be truly successful in treating your banded catsharksupplementingsupplementing.
Hope this helps a little bit!
