Have yet to use it as I'm still setting up. Looks like a nice item for feeding.
Maybe I just have dumb fish. There just doesn’t seem enough space for my fish to get at the blood worms.
It works, but the slightest bump causes it to come off the suction cup.
Not only do I use these for feeding frozen foods, I placed mine under my autofeeder to extend my fishes ability to graze.
I've mixed a number of floating and sinking pellets with flake food in my auto feeder - all very small sized - and I found by preventing the sinking pellets from falling immediately to my substrate with the cone my mid-level feeders have a better chance of getting the food as it softens and works its way out of the colander which is getting outflow.
All of my top level theaters take from it greedily.
