Okay, so I've been using these Zelerdo feeding rings for about a month now, and wow – what a difference they make!

First off, the suction cups actually STICK (unlike some other brands I've tried). I have them in my 20-gallon community tank with a strong filter current, and they stay put. No more chasing flakes around the tank!

The size is perfect – not too big to dominate the tank, but large enough that my tetras and guppies can all feed comfortably. I love that the black color blends in nicely with my setup.

Bonus discovery: They're amazing for corralling floating plants too! My water lettuce used to get sucked into the filter, but now stays neatly contained.

Only minor gripe? When the water level drops during weekly changes, they don't adjust perfectly. But honestly, for $10 for three of them? Absolute bargain.

My fish are eating better, there's way less waste, and my tank stays cleaner. Total win!
