I have microworms, vinegar eels and grindal worms. Setting up starter cultures of microworms and vinegar eels would be very easy.
I don't have the stuff on hand to start a grindal starter - plus it does have grain mites - so if you don't want those, you might want to look elsewhere. But if you don't mind them, I could give you a portion of my culture to start your own.
But not sure when I would be able to meet up.
