Hi,

my ADFs don´t really eat pellets. I´d rather recommend to look into other sorts of frozen foods, e.g. brine shrimps, black mosquito larvae, mysis, tubifex etc. If you have gravel instead of sand, very small foods like daphnia will probably sink in before the frogs can find them. Glassworms don´t sink, but your fish would eat them before the frogs even realize that there is food You can also cut earthworms so that the pieces are small enough for the frogs; they are very healthy and calcium rich.
