I do!!!! That's actually pretty much all my fish will eat excluding live/frozen foods!
It's one of the best foods out there at the moment as it contains both garlic and spirulina. Garlic is a natural anti-parasitic food and thus is great for Betta's, they also love the taste of it so it's common for picky fish to like this food.
I tend to vary my feedings based on the fish, my younger boy's get 6-8 pellets once a day while the older boy's get just about 5-6 and my constipated boy usually get's around 4 pellets a day since he has issues digesting. If I find that my boy's are looking particularly skinny, I'll even feed them right up to 10 pellets if I feel the need since they are so small. I use the Betta Formula btw but the small fish is just as good, actually has more protein in it.
And the girls in my sorority, well I just throw some pinches in and they eat whatever is in there
