I have lots of pods in my tank. Copepods, Isopods, amphipods, absolutely packed into my rocks and sandbed. At night and feeding time the rocks are really alive and during the day the glass is covered in "sugar". I want to add to this mix of fun fish snacks with live mysids and I'm wondering where is the best place to get a starter culture. I am not interested in them as a recurring order to feed any particular fish, just want a jar I can pour into my fuge and display and hope for the best. If it doesn't work out, oh well.
