Concerning the diet - it is a good idea to feed your frog a variety of foods. However, it has been my experience that Tetra's Repto-Min is a great staple food and I've been using it for 30 years with great success. I also hear that many Xenopus keepers feed their frog bloodworms. This is a bad practice since bloodworms have little or no nutritional value and may cause excessive bloating. If you must feed bloodworms, do so only as an occasional treat.

Just a FYI.
