Pretty expensive for fish food!Amazon has flat brine shrimp hatcheries that look like black flying saucers. If you read the reviews, they are flimsy side, but I carry them on scrap wood left over in garage from a project. That helps me carry them around with water inside (from kitchen to where they sit to hatch with box over them and an incandescent lightbulb.
Eastern Aquatics is just in Lancaster PA, so shipping isn't as bad for you as me. They are doing overnight because I'm in TX and they'd be cooked black worms otherwise
