Are blood worms ok for saltwater fish?

[Myka]

Blackworms are a really good trick to have up the sleeve. They can also help to trigger spawning activity in fish that need a bit of a tip over the edge. Locally, I order them through Petland. A 5" ball is $20. They usually come in with lots of leeches which have to be picked out. The last batch I ordered died in only a few days, so I didn't even get a chance to feed any to my fish, but usually they live a few weeks in the fridge.

Piscine Mysis are freshwater, certainly. Piscine is based in the Okanagan of BC. The Piscine Mysis are an exception in that they have an outstanding amino acid profile which is why I said, "Nutritionally speaking, saltwater organisms generally have a more complex amino acid profile than freshwater organisms."
