OIIKI 2 Pack Fish Feeding Ring, Aquarium Fish Floating Food Feeder, Square Shape with Suction Cup(Black)

I like the simplicity. But, it lacks adjustability. My 5 gallon fish tank came with a plastic cover with a flipable lid. I'm unable to put food in with the cover on. But, I'll leave it for now to keep food from floating around in a tank or going into the filter.

But the little round one is just too small for my big tanks. But both are well made and the suction cup stays firmly attached.

Was hoping to put the fish food in it and the fish would eat but there's really no use for it as the food starts to sink and the fish eat it at the bottom of the tank. But the idea was nice.

These fish feeding rings look good and function well! HOWEVER, although the fish feeding rings looked new, one suction cup was REALLY ratty, fogged over, and old looking and almost looked like it was used... I'll keep the product. Just not happy about the one suction cup. (Pictures attached) I'll be using the new looking suction cup interchangeably, but am sad because- well- what if I wanted to use both? Oh well...

Thought the suction power was good at first but after a day it just would no longer stick. I just let ring float in the tank now. But it does great keeping the food in one place. I noticed that small fish pellets tend to foat around the middle of the ring for a while before it starts to gravitate towards the edge of the rings.

The portals are made with plastic and foam. I prefer to use them without the suction cups. Definitely recommend!

As the title states, suction cup is weak and doesnt hold the ring to the side of the aquarium

These float, but the suction cup didn’t work at all.

It broke the first time I tried to move the suction cup
