Okay, thanks for all the info about the sea horses. I have a new question now. I feed my Naso , SEAWEED SELECTS made by Ocean Nutrition. One box of 4 sheets will run me six bucks. I was at the Giant grocery store yesterday. They have a asian guy that makes food for you while you wait. So I asked if he knew where I could get Seaweed. Right there ! It is a bag of 5 big sheets and was only $1.75. Can I use this? It says Southern Tsunami (brand) All Natural Sushi Seaweed. Also I've been using Beth's recipe and the other fish love it. The Naso won't touch it though. Is there a recipe out there for the other guys? Thanks.
