Cohl, you should be able to find plenty of diversity in food suitable for your shark. Any local grocery store has Shrimp, fresh white fish(may differ by store), scallops, and clams. Whole Foods is a great place to get many things that you can't find in a normal grocery store. I get some of these items there....Scallops, Clams, Oysters, fresh white fish, squid tentacles and tubes. I usually make about a months worth at a time to freeze by cutting the pieces that the shark can swallow whole and soaking in a vitamin supplement(I use Selcon or Zoecon, Iodine(leads to many problems with goiters in sharks if there isn't a sufficient supply in the water or their diets), and Marine C.) I then bag them into single servings and freeze them. Then, on the day I am feeding, I pull the bag out and set it on the counter until thawed. I spear the pieces one at a time on a long feeding stick and make sure not to get a lot of the extra juice into the water(can lead to water problems, or add to them). I do not believe it is necessary to order any shark specific products as they as drastically more expensive. I have had a bamboo shark for over 2 years and he has been very healthy without ever feeding him anything but the mixture I have above.
