Yeah, you can feed both
crix and mealies to them.
We don't have beardies, but we do have many others that eat
crix and mealies.
We get them about a weeks supply at the time for
crix, keep them in a 5 gallon with a screen lid and use a small critter carrier to shake the
crix into, dust and then to deliver to the critters.
Works really great that way, with few escapes and easier to dust and deliver.
Below is the critter carrier we use to dust the
crix and to transport them from the
crix tank to the animals tanks.
Easy to use.
Flip the hatch open, insert the entire carrier into the
crix tank, skake
crix off the egg crate directly into the hatch, close it, add the dusting powder of your choice, shake gently, then place into the animals tank with the entire lid off and on its side.
