Tarantula Nutrition tools: what they help with
These calculators work out what and how much to feed a tarantula: daily calories, portion sizes, feeding schedules, water needs and which foods to keep away from it. Diet is the single biggest thing most owners control. Getting portions right prevents obesity and the many problems that come with it in a tarantula.
What to know about nutrition and feeding for tarantulas
A typical adult tarantula weighs 20-150 g. Tarantulas are insectivores, which shapes what you feed and how much.

Weigh food rather than using a cup or scoop. Measuring by volume is one of the most common reasons pets are overfed.
