I was looking for an artema hatchery dish (apparently its an obscure thing to find) a while ago and found it on Brine Shrimp Direct.com These guys ship incredibly fast to Colorado and always give you a lot of bang for your buck. I've ordered brine shrimp cysts from these guys and spirulina powder. They are probably the best deal for fish food. The only downside is that they don't sell live stock. A+
