Hi,

I personnaly use calcium power without D3 and calcium power with D3.
D3 is necessary to fix the calcium for the frog, but, you should not use D3 too much.
Too much vitamins for amphibians is really bad.

What I do is "calcium + D3" on 1 or 2 insectes per month (Not much !) and "calcium without D3" every two days on 1 insect.

Also I have a friend who has a budgett's frog, two Pyxies and who never uses calcium power => Frog never had any groth problems.

Various feeding is the key : crickets, locusts, roaches, mices and nightcrawlers are the most advised food for our Pyxies.

Be careful also with gold fish : they contain some bad things for frog health.
