I've read a bunch of care sheets. Many say to use a calcium supplement with D3. Others say not to use D3 and that the D3 can build up to toxic levels in leos. So, what is the real deal? I've been supplementing with Reptical w/D3 along with a muti-vitamin since I've been keeping leos (about 6 months). I feed a staple of mealworms with crix occasionally. What do the experienced breeders use. Thanks...
