I bought this divider for my two betta fish who were constantly fighting. After placing the divider, they stopped chasing each other. The acrylic is very clear and the holes allow good water flow. Installation was easy and the suction cups hold well.

Works well for separating fish by size. The bottom slots help with waste drainage, which I noticed improved water clarity. A little bit of adjustment was needed to get the suction cups aligned properly.

The transparency is excellent and I can see every detail of my fish. The divider doesn’t block the view and the fish seem calm now. I’ve used it for over a month and it’s still in good condition.
