Specially formulated diets for a specific species should not become a large part of the diet of another animal. Although it would likley not be harmful to give a little of the parrot food to Star Tortoises, it should never be a large, or even regular part of their diet. Best to find out what the Stars eat normally in their wild habitat and feed THAT to the tortoises. Good luck.

>>Is parrots food good for srilankan star tortoises. Reading the ingredients in particular brands seem to be ok. Are there ingredients that are not good for them?
