Some people use garlic in their gel food (I seem to recall) but the concentration would be minimal and I don't recall if it was oil or crushed garlic.
I tried doing this with crushed garlic. It STUNK and the fish refused to go near it

what I do every so often is to smash a clove of garlic on a paper plate, and put the food in the juice from the garlic. I just roll it around in it for a bit to soak up the garlic juice.
Great suggestion Debbie, I may try that!
Garlic is great for most animals. I give my dog supplements which contain a lot of garlic, it's suppsed to even help with fleas. I think getting goldies to eat it could help ward off sickness.
