Initial Impressions and Purchase
I recently purchased the Top Fin Tank Divider, specifically intending to use it in my 10-gallon aquarium. Unfortunately, a 10-gallon size wasn't available, so I opted for the 20-gallon version instead at a price of $17.99. The price point immediately raised a red flag; for a seemingly simple product, eighteen dollars seemed steep.

The initial packaging seemed unremarkable. However, this initial innocuousness quickly proved deceptive. The product's fragility became evident almost instantly.
Right away, I noticed the thin and flimsy nature of the plastic. I had to modify the divider by cutting it down to fit my 10-gallon tank, adding to my initial concerns.
Flimsy Construction and Poor Suction Cups
The plastic's flimsiness was a major issue. The entire structure felt incredibly fragile, and this impression was unfortunately confirmed upon installation.

The divider relies on suction cups for support. These suction cups, however, were hopelessly inadequate. They failed to adhere properly to the aquarium glass, rendering the divider largely ineffective and prone to frequent collapse.

Adding insult to injury, the small plastic pieces meant to secure the divider to the tank were extremely brittle. One broke during unpacking, and several others broke over the course of two months.
Overall Assessment and Alternatives
Overall, this Top Fin Tank Divider is a disappointing product. Its poor construction, ineffective suction cups, and brittle plastic make it a frustrating experience. It definitely isn't worth the $18 price tag.

While tank dividers might not be the most durable long-term solution in general, I've used other dividers in the past. The quality of this Top Fin divider was significantly inferior. It simply doesn't hold up well to the stresses of an aquarium environment.
I strongly advise against purchasing this product. For a more reliable and longer-lasting tank divider, explore alternative brands and designs.
