I don't have any of those, but I do have a hammer (same genus as frogspawn) who will occassionally take small mysis, brine or cyclop-eeze. I've heard people feeding the same to bubble corals, and I bet they'd work for the others as well, but that's just a guess. I know the first two don't actually need to be target fed, but from what I understand, most stoney corals will benefit from occasional feedings.
