I've been using these feeding rings for a few weeks now, and they've completely transformed how I feed my fish. No more chasing flakes around the tank or watching food disappear into the filter!

The round one fits perfectly in my 10-gallon tank, while the square one works great in my larger community tank. The suction cups hold strong even with my bubbler running, and I love that I can adjust the height as my water level changes.

My guppies and tetras quickly learned to swarm the rings at feeding time. It's so satisfying watching them eat without the usual frenzy - even my shy neon tetras get their share now. The black color blends right into my tank background too.

Unexpected bonus: I've started using the square one to corral my floating plants. Keeps my water lettuce from taking over while still letting light through. Two solutions in one!

Only note - like another reviewer mentioned, these work best in open-top tanks. My nano tank with a lid makes placement a bit tricky, but it's still manageable.
