Let me tell you, this little glass feeding set solved SO many problems in my shrimp tank. The 8-inch tube with suction cups stays perfectly vertical in my 5-gallon nano tank, keeping food from drifting into unwanted areas.

The genius part? That white stopper at the bottom. My curious cherry shrimp used to swim up into other feeding tubes and get stuck - nightmare over! Now they can graze safely while their food stays contained in the clear dish below.

Pro tip: Position it so the top opening is just above water level like one reviewer mentioned. This creates perfect water flow to deliver food straight down without any floating debris. My bottom feeders finally get their fair share at meal times!

The glass quality surprised me - thick enough to feel durable but crystal clear for monitoring leftovers. Cleaning is a breeze too; just a quick soap rinse prevents algae buildup.

One small gripe? The feeding dishes are indeed compact (about 2 inches across). For larger tanks, you might want to use multiple sets or consider their model with attached dishes. But for shrimp and small fish colonies, it's absolutely perfect.

After three months of daily use, I can confirm: no cracks, no cloudiness, and most importantly - no more wasted food rotting in my substrate. Total game-changer for maintaining water quality!
