Okay, so I got this acrylic feeder cup thinking it would solve all my fish feeding problems. Spoiler alert: it didn't. But let me break it down for you.
The good? The suction cup is STRONG. Like, 'might outlive my fish' strong. And the V-shape design is actually pretty clever for keeping worms contained - when I actually used it for feeding, that is.
Here's the weird part - it's become my accidental plant holder! The space is perfect for small aquatic plants, and they look adorable stuck to the tank wall. Not what I bought it for, but hey, happy accident.
Now the bad news: water level issues galore. If your tank is filled normally, say goodbye to keeping food inside. My guppies treat this thing like a buffet line - swim right in and grab what they want. I tried modifying it (yes, I got out power tools) but still no luck.
Final verdict? 2/5 for feeding, 4/5 as an impromptu plant display. Maybe buy if you want both? Otherwise keep looking for a better feeder solution.
