Haven't gotten them yet but will definitely post when I pick up tomorrow.
Knowing my fish (2 clownfish, 1 baby blue tang, 1 leopard wrasse, 1 orchid dottyback) they will destroy those blackworms!
I feed them a tiny bit of ROE from reef nutrition on occasion just to provide enrichment/excitement. Imagine dozens of tiny white balls floating around your tank. My fish go NUTS for them. Pretty fun enrichment activity for the fish. So I'm 100% sure they will love these worms.
