Hi, all. I posted this as a comment in another thread, but it honestly deserves a thread of its own.
Brineshrimpdirect.com has a really neat hatchery dish for BBS that does not require an air pump. And for a limited time, they give you an entire spice-jar-sized batch of BBS eggs when you buy it. Just the BBS eggs alone are worth more than the price of the hatchery.
I bought this and am really happy with the hatchery, though you do have to leave the light on in the room for the shrimp to swim toward the center receptacle. It's really a great deal for breeding!
