That might be your issue. As mine got older, he started to ignore guppies but would go for minnows immediately. I've run into that with frogs as well; as they get older they will ignore food items that are very small. Have you tried frozen/thawed fish?

My supermarket sells fresh trout and salmon. I have started asking them to cut it into strips and put it in their freezer (which gets much colder than mine) for a few days until I return and pick it up.

Gets rid of the parasites without worrying about the chemicals used on fish sold as "frozen". I also eat a lot of fish so the guys in the fish/meat department know I am a regular and are happy to cater to special requests.

For the OP, i read somewhere that putting the b vitamins in their water can help, putting on the food doesn't work since the enzyme will destroy the vit b, but if the animal is going a few days between meals then having supplemented water in between meals may help and I guess theoretically some is absorbed without being destroyed.
