Feed the right sizrd crickets
But feed as many as they'll eat in 15 minutes twice a day along with fresh greens available at all times.
Id guess probably 20 crickets a day. I recently started a dubia roach colony simply because we spend so much on feeders for them.
I was shocked how much they'll eat and how nuch care they are compared to snakes, so be prepared!
Thata just my opinion
