Cone Worm Feeder 2-3/4" diameter x 3" high
Been Using these for Years
I bought my first cone feeder over 12 years ago and it's still on my tank. I finally decided to replace the old one with a fresh one and get a couple for my other tanks. I honestly only rarely ever bother using the bloodworm cone. I always just use it to keep pellets or flake food from getting blown around the top of the tank, ending-up in my filter or going down the overflow.
I always feed very small amounts and this is feeder ring is key. The fish know their food is going to always be in the ring and since it can't float away nothing gets wasted. A tiny pinch of food and everybody top feeding gets a little.
The cone works with frozen bloodworms very well but any worms that float won't get eaten unless you take the cone out after the sinking worms are all gone. I have used it with other frozen foods and most of them worked out just fine. The rule seems to be if it floats use only the ring and if it sinks use it with the cone.
The only top feeding fish I've ever had that had a hard time finding food out of it is my betta. He eats from it, but I have to sometimes lead him to the center of the ring with my finger.
The only con I can give it is it's hard to fit the suction cup to the ring. It's such a tight fit. Honestly, For my original one I ended up trimming the plastic pin down with a knife to make it thinner. For the new ones I put the suction cups in a cup and poured near boiling hot water over them to soften them. Once they stretch out a bit it's much easier.
