How often to feed fire belly newts?
Depending on your newt, you may have to try a variety of food sources. Bloodworms, frozen or live, seem to a favorite among newt keepers. These (especially the frozen bloodworms) are quite readily available at pet stores. They may also eat earthworms (chopped), brine shrimp, glass shrimp, daphnia, and freeze-dried tubifex cubes. Floating reptile/amphibian sticks such as Repto-Min can also be fed, although many newts refuse them. Larger newts, particularly the larger Japanese fire bellied newt, may also eat feeder guppies if offered. Fire bellied newts do not have to be fed every day – every other day or every three days is often enough. It may take a little experimentation to figure out how much and how often they should be fed, but you can try to judge by their growth and body condition (fat or skinny) and whether excess food is being left (which will cause toxins to build up in the tank).
