I have one that I used to "try" to feed a mandarin goby with. All of the other fish hung out in front of it and ate them as they were hatched. I think it was 30 bucks to buy one and a vial of brine shrimp -- really cheap to use actually. I haven't had it in my tank for quite awhile but thinking about doing it again just for a treat plus it's kind of cool to watch them hatch and swim out.
