Well, We got some Minced garlic in the fridge. And I decided to smear a little on a piece of Nori. Once placed in the tank, All the fishes went nuts. The only one eating it was the Yellow tang, but the Garlic sure enticed the other fishes too

I don't feed the pieces to the fish on purpose but some does get into the tank and the fish will usually spit it out. My rabbitfish does actually eat small chunks, hes a garbage disposal though :lol:

Garlic extracts work great as attractants, but if you are venturing into the grey area of using garic a a treatment or preventitive, use fresh garlic. There has not been a lot of research into the medicinal use of garlic, its still kind of a grey area. Garic has several active ingredients mostly sulfur based, (allicin, diallyldisulfide, diallytrisulfide) but these are quickly oxidized and loose there potential benifit. There is some evidence that these active ingedients have a anthelmintic effect on nemitode worms. I have myself used garlic (25%) in feed to rid discus of nematode worms. It is also believed that garlic has anti-paristic properties. A lot of people swear buy adding garlic extract to food to prevent and help treat ich. I myself will treat ich buy adding crushed garlic directly to my reef tank in a mesh bag (haven't had any noticable adverse consiquences, but who knows if this is a good idea. wouldn't want to recommend it just in case, but it works for me. Haven't come accross other people doing this, most just add it to food.)
