I currently keepseveral hognose, and have bred them in the past. I now Westerns/Mexican, Eastern and Southern and for some reason they all seem to go of feed for a time for no apparent reason. I have noticed this to be more so with males.

I have all my more finicky feeder accepting salmon scented, tuna and toad scented pinks. They will grab them with gusto. I bought a can of canned salmon from the store. I dumped the contents in a freezer bag and froze it. Now when i feed the more finicky hogs, I rust rub the thawed pink on the frozen salmon and it has worked for every baby that is a reluctant feeder. You can buy a frog from the petshop. I have used tree frogs in the past.
