Jellyfish,
	 
	You could go get some of the expensive GarlicX stuff from a LFS if you wanted.  However, it is much cheaper (and just as effective IMO) to go to the grocery store and get a small jar of minced garlic and use the juice.  Whenever I put a few drops on my nori, the tank turns into a feeding frenzy.  Even my lionfish looks at it longingly as if he really wants some.
