I know overfeeding can be risky to juvies and p'lings but I don't know about subs and adults. I would imagine that one pinky per week would suffice though. It may have been very hungry for the moment. I'd let it settle with what it's eaten for a week or two before feeding again.
LOL! I know cleaning up small vertibrate prey remains sucks! Pedes are messy eaters for sure!
