Yes... feeding in-community can be a very difficult task, and is why my frogs are now in a species-only tank. It's just too hard to make sure the slow-poke frogs get enough and the faster fish don't end up with bloat (that is, unless you're Olympia - her Atilla is the exception to the rule!)
If you can get them to take pellets, that's awesome! Mine won't. . . If yours continue to eat mostly bloodworm, you *may* want to look into getting some other types of wet-frozen froods (brine shrimp, mysis, etc) to mix things up a bit for them. It's usually best for them to be fed on a variety of foods. Mine love tiny bits of raw tilapia fillet, which is cheap and easy to find in the grocery store.
