Why buy that stuff when you can blend fresh seafood yourself? shrimp, scallops and whitefish mixed with some fresh garlic, nori and some zoe is what I use. If you have a better market, you can find some nicer stuff. I spend about $8-10 and have enough food to last 6 months.
When I feed, I break a hunk off and just break it apart with my fingers in the water. No preservatives and very healthy. Most my fish come up and eat from my hand.
