I've been told that it is good to feed garlic sometimes when feeding.. it helps from parasites like ich and anyother ones out there??? is that true??? if so how. ***)
its a way to prevent ich. it boosts a fishes immune system and its also entices the fish to eat. i use it and i dont ever think id go back to not using it.
Use a garlic press to strain it down as fine as you can get it, or puree it in a blender, then I mix it with hikari freeze dried artemia, and ground freeze dried ocean plankton. The fish LOVE it.

There are some links in the thread that explain a lot about allicin and how processing makes it degenerate into useless forms. It should also be used very quickly as the allicin degenerates naturally between 1 and 6 days.
