Review on Gallon Aquarium Divider Suction Cups by Sharon Hill

This product is good and bad at the same time, I like that it has a dark mesh. This keeps the filtering working properly and my bettas barely notice each other. The problem is that I ordered this based on the size of the aquarium. (We have 2 bettas in a 20 gallon aquarium). After reading the reviews I ordered a 20 long, assuming I would have to cut it to fit. Not this case. The delimiter is too short! I had to put a ton of bricks under it to make it work. So it looks like my tank has a hill in the middle. It works, so I used it anyway.
