I have the Lee cone and have tried it once. It was a lot bigger than I thought it would be. I have white skirt/glow tetras in a 20 gallon and my fish couldn't figure out how to feed from it. Dumb fish? Lol..overall it's a good product. I now feed blood worms via tweezers. I did come across this item just now on Amazon. Wonder if it's just as good?
