Where do you get your info. Pacmans especially. They don't naturally produce D3 without or atleast not enough without a supplement or UVB rays which are also contained in natural sunlight. They benefit from 4 to 6 hours a day of UVB but the problem is that UVB lights are almost always too bright. For Pacmans ofcourse since they live on the forest floor. Pyxies in the wild probably receive tons or D3 since they do occationally come out in the sun. Its risky to not provide a calcium supplement.

Not really sure this is even helping the thread at this point, but if the above doesnt prove that suppliments are much more optional than required, personal experience. I have currently 18 C. cranwelli, 8 Fantasy, and 14 Pixies. None of which have ever recieved suppliments or additional lighting of any sort. They have grown to full adult size in sweater box style rack systems over the years.

I also have boa constrictors for much longer than I have owned frogs. My boa's are almost neve exposed to any light whatsoever. Yet they grow, feed, and reproduce with no added suppliments. Boa constrictors are exposed to a lot of sunlight in the wild yet reproduce just fine in captivity.

My point is suppliment D3 is similar to Multivitamins for people. You use some of it, but most of it you pee out
