Okay, let me start by saying this little acrylic ring solved a MAJOR drama in my tank. My goldfish were getting bullied by my sneaky turtle during feeding time – he'd vacuum up their flakes before they even had a chance! This feeder creates a peaceful 'dining zone' where only fish can access the food from below. Genius!

The suction cup? Here's the trick everyone misses: press it FIRMLY onto clean, dry glass FIRST, THEN screw the feeder onto it. Done right, mine stays put for days (even with curious snails bumping into it). Though fair warning – if your water level drops too low, it becomes a floating buffet mess.

My betta absolutely adores it now – no more Olympic-level swimming to chase pellets! Bonus discovery: he naps inside the ring when I tilt it sideways post-feeding. Pro tip: remove that pointless clear plastic sleeve around the suction cup immediately – instant upgrade to its grip.

Downside? It's completely transparent, so my turtles kept bonking their noses trying to reach food through the sides. A colored rim would've helped train them faster. Also, aggressive fish might still knock it loose – not ideal for tanks with rowdy swimmers.

For small to medium tanks? 100% recommend (just monitor that water level!). For larger/active fish setups? Maybe wait for a sturdier version.
