Have my GTF that are about 5 months old now - they've only been living off of fruitflies that I have gotten pretty good at culturing. I dust everyday alternating with calcium powder and vitamin powder. We don't have access to pinhead or small crickets around here - our local petstore only has 1/2 in to 1 inch crickets. I occasionally find moths flying around so I give these to them sometimes.

Is it ok to just continue feeding them with fruitflies?
