Yea, those are the ones that I was thinking about. Do you have any pictures on the one that you found that seems to be good? There are just too many to choose from.
I bought mine from H-Mart too for only a few dollars. It's comes in 50 sheets. Company is called Wang-Korea. The type is called Dried Seaweed (Laver) - Algue Sechees. My fish love it. I tried to look for something as natural and least processed as possible. I'm not an expert, but I avoided getting anything "roasted". (Don't mind the expiration date in the pic - it's algae - I'm not eating it and I don't think it really expires lol)
