Nightcrawlers are super affordable and ALL of my frogs love them. My peppermint will leap (I know...the fat little SOB's leaps compared to others aren't much) for a nightcrawler in the tongs or waterdish. My Pyxie...sad...lol, I almost wrote Pyxies (I sold my females to Mike)....anyway, he eats them by the mouthful. I put about 8 at a time on a plate in his cage (spagetti), sprinkle on a little calcium (parmasean cheese) and he destroys them.

No need to feed any other 'worms' IMO. Variety is the key as many have said multiple times on different threads and I think the other worms/feeders make for great treat to add that variety.
