Aquarium Feeding Ring Floating Rings Food Feeder Feeding Trough Square with Suction Cup for Fish Feeder

honestly， I bought this one not for can opening, but for opening my salt container. The opener works very well, you can see the cut edge is sharp and clean, it is very easy to use. just mount it on the cylinder edge and screw the handle side. the opener designed well with fine manufacturing. This tool makes kitchen life easier, I like it.

Reasonable price and good product

The black worms are happy in my fish is belly

This is garbage, the worms don't even fall out or can be eaten. all clogged.. the slots are all together, looks nice, but completely useless.. Unless you just want to dirty your tank//\\..

I thought these feeders might keep the tank cleaner and allow my female cichlid a chance to eat more, but it didn’t work out that way. The male cichlid ate the food from both and the remaining food did not stay in the confined area, it sank into the water and the tank was as dirty as it was before. It may be better for small fish. I tried using the baskets but the food was too large to go through the feeding slits.

Great for value, can use the ring separately too, suction cups small so if you have rough eaters maybe get a bigger suction cup to change out- besides that perfect.

Great for feeding fish and keeping tank clean

The media could not be loaded.  Everything is good. But, the most important part, the suction is a cheap silicon suction. It does not have enough power to sucks to the glass more than an hour.This product is useless if the suction does not do it works. It is now a floating feeder.
