I will look for some nori this weekend and see if they will eat it. Thanks! What about fish meat? Can I feed them Tilapia? If so, how should be prepared? UPDATE: Hey guys, I found some nori, but this nori expired last 2011. I have not checked another store yet, but the brand is Yamakawa and it is sushi-nori. It cost about P100 (I believe $2). Will this have chemicals in it? Thanks!
