i was told today that a dish of water may not be safe,and that i should stick to spraying them,and possibly with a little calcium in the water..
With regards to feeding on the substrate,can you elaborate?
Basically if your keeping them on sand, and you feed them in their enclosure, they are more likely to get a mouth full of sand when trying to catch their food.
If you take them out and put them in a tub to feed, with no substrate, they will have no chance of copping that mouth full of sand.
That way no bugs get left inside the enclosure, especially crickets, which can cause damage to your dragons of left in the enclosure also.
