Well, since springs are not typically dusted (I wanted to say "can't be dusted", but that's been debated here), and since most keepers (I wanted to say "everyone", but...) are agreed that dusting all prey items is important, then too frequent snacking on springs might hurt.de-populating your culture and giving them some extra snacks more frequently certainly won't hurt. I feed mine a small tablespoon worth of springtails about once every 2 weeks.
Yep! Definitely not saying to offer a springtail-based diet here, but I have seen my vents pick at springs more than larger frogs (tincs, terribs, leucs) - so would just make sure to restock the vivarium population more frequently for those. A quick dust on the spot where you dropped them into the viv also can't hurt.Springs are a good 'in between FF feedings' prey to hunt for, and are very important for new morphs, but otherwise should be offered in moderation, at most.
