Others will prove to be finicky eaters. Try a variety of foods until one is taken. It is generally not necessary to vary the diet much. Occasionally a spider can be induced to eating a piece of meat. Select lean raw beef if you try this and dangle it on string to elicit an attack response.
Tarantulas have also been know to eat baby mice and even fish in captivity.
Feed the spider about once or twice per week. One or two crickets per week is sufficient for a large tarantula. Smaller spiders need smaller food and may need to be fed more often. Feeding may take 20 minutes or over a few hours. Some spiders will wrap their prey and save it for later.
