Yes, I suppose I am lucky. I'm not sure my frogs even see/notice the frog bites, but the fish sure do and love them!
It's pretty funny to watch the frogs eat the flakes--they sniff and sniff and then lunge at the flake!. I usually have to "aim" the flakes their way b/c they apparently don't see well and have to smell their food.
I'm going to try a couple of more things to get them to try to eat the frog bites, but at least they are not starving.
Good luck to everyone who has picky eater frogs. I'm glad mine are little piggy frogs.
