Well...my adults eat every 5-6 days. My babies...have been eating worms more than anything else...but I try to switch it up with fish and pinkies too. I definitely wait three days before feeding again if I gave them pinkies in the last feed...since it takes longer to digest. I would say they each get maybe...I'm guesstimating here...7 little bites of worm or pinky or fish each time I feed...cut into very tiny pieces mind you. As soon as I see their tummies looking really full...I take away the food. I did not end up feeding them last night...which would have been two days since the last feed...because they still have full looking stomachs, to me. Unfortunately...this means they may have to go 4 days this time because I am leaving for the day soon...and won't be home until late tonight.
