@jeffaquarius - Your fish may not touch garlic, but it could also depend on the breed, my test was successful with pure garlic granules.
@BBradbury - Thank you for the info.
I'm glad to see it doesn't negatively affect your fish in the long haul, that was another question in my mind.
If you try this, of course check the ingredient list for any preservatives, chemicals,
or other potential hazards for fish & humans alike. My test was with organic garlic granules. So the 1st feeding of the day, they hadn't eaten all night & were pretty accepting. I also rotate flakes, pellets, algae wafers, so they aren't picky eaters & used to change.
They darted at & ate the water-soaked garlic granules right away
(if I had garlic powder it might even be better because my tetras are tiny .75 inch). 28hrs so far & no adverse affects or bloating of any kind. It was also great they sank gradually, and made for an exciting "chase" as opposed to floating food.
I will note that the flame tetras after 1 or 2 granules swallowed, they started to get picky & would spit out the 3rd bite. ^_^ My white cloud & the glowfish tetras didn't mind & polished off the rest of the garlic before it hit the substrate.
I know the benefits of fish & garlic are debated, so I will continue looking into it. But for now, I think I will add soaked garlic granules to their food rotation, about every 4th day.
