Let me start by saying this little feeding ring is ADORABLE in my betta tank. The clear acrylic design blends seamlessly, and the dome shape does prevent food from scattering everywhere. My betta used to chase floating pellets like a maniac – now he eats like a civilized gentleman!

However, that single suction cup is its Achilles' heel. Like other reviewers mentioned, it pops off constantly unless your tank walls are perfectly smooth. My solution? I superglued an extra suction cup (stolen from an old thermometer) and now it stays put. Why didn't the manufacturer just include two cups?

The filter balls are the unexpected star here! Watching them dance in the bubbles is weirdly therapeutic. They do collect gunk surprisingly well - I rinse them during weekly water changes. Pro tip: Soak them in tank water before first use to prevent that 'new plastic' smell.

For turtles? Big nope from me. My friend's red-eared slider treated it like a soccer ball within minutes. The small size (about a credit card length) works for nano fish but is comically tiny for anything larger than guppies.

Final verdict? At this price point, it's a fun novelty item for small fish keepers who don't mind some DIY fixes. The filter balls alone make it worthwhile, but manage your expectations with the feeding ring's stability.
