Bread as fish food...no. For several reasons. It can swell in the stomache, causing digestive problems, will foul your water pretty quickly, contains little nurtitional value as a food for humans, even less so for fish.
Why would you want to feed between feedings. Overfeeding your fish is worse for them than underfeeding. Over fed fish are more prone to develop constipation and anal prolapse. Tanks that are overfed generally have water quality that is much harder to maintain at healthy levels (high nitrates, ammonia and nitrite spikes).
If you are looking for good supplemental foods for your fish to go along with a staple of prepared pellets/sticks/flakes, then do some research into the fish you have. What do they eat in the wild? Are they omnivores who would benefit from live crickets, worms, pieces of soft fruit, blanched veggies? Are the vegetarians who would benefit from a slab of blanched zucchini or cucumber.
