Nightcrawler question?

[MatthewM1]

My new little Cranwelli went right for the little earthworm chunks from the tongs almost immediately his first night home! He ate 3 little chunks and prolly would have eaten more if offered but I was a little nervous to accidently over feed him. Should I be using the 10 min rule for feeding him or is that just with crickets? He's about 1.5 inches from snout to vent.
