From the fry I've observed, MOST will NOT eat powdered foods UNLESS they see another fish fry of similar size eating.
I use various magnifying glasses to watch their little beady newborn eyes as they analyze the microbes around them and decide what to taste & reject. It's absolutely entertaining
. Poppy seed sized gourmet taste buds.
I tried dozens of various dried foods for over a MONTH & gave up. As most who've tried already know, if you add food & they refuse, depending on the amount you drop in.... the water will get ruined & once ammonia starts to show up, it's almost instant death if your filter isn't established.
You may attempt feeding crushed
prepared foods into powder @ your own risk.
I have 3 different types of auto feeding gadgets I tested out. I'm so glad I didn't pay anything for any of them, but they all NEED tweeking/adjustments before you can trust them to function like they claim.
I've tried to even create a funnel out of different waterproof materials to redirect the dropped food into the tank, but that didn't work due to condensation build up.
After I had time I look at the mess those things created @ the back of the tank, I rinsed the auto feed gadgets out of clumped up ruined fish food & put them in storage.
I'm pretty sure there's 50 different types of automated feeders out on the market now.
I find them more collectible then functional.
I have the 2 on the right. I forget the other brand I have.
