Let me start by saying I was genuinely excited to try this feeder. The idea of a transparent, suction-cup-mounted cup for live food like red worms and brine shrimp sounded perfect for my community tank. The glass construction is indeed sturdy and clear, making it easy to monitor food levels—no complaints there.

However, the suction cups are a major letdown. Like some reviewers mentioned, mine arrived slightly warped and struggled to stay attached. After a few frustrating attempts, I managed to get it to stick by wetting the cup thoroughly, but it still occasionally detaches unexpectedly. Not ideal when you’re trying to keep your tank tidy.

The slots at the bottom? They’re a double-edged sword. For smaller live foods like baby brine shrimp, they work fine, but blackworms? Forget it. They either take forever to wiggle out (we’re talking hours) or escape en masse within minutes if the slots are too wide on your particular unit. I ended up using mine as an impromptu planter for anubias—which actually worked great!

On the plus side, my fish did eventually learn to associate the cup with feeding time. Watching them swarm around it is entertaining, and it does help contain messes compared to free-floating food. But between the inconsistent suction cups and hit-or-miss functionality with different foods, I can’t wholeheartedly recommend this unless you’re prepared to tinker with it or repurpose it creatively.

Final verdict? It’s not terrible if you get a good one (check those suction cups immediately!), but there are definitely better-designed feeders out there for serious aquarists.
