Top Fin 5 Gallon Divided Betta Tank: Setup and Features
The Top Fin 5-gallon divided tank is a fantastic option for housing two betta fish. Its divided design ensures each fish has its own 2.5-gallon space, meeting the minimum tank size requirement. The tank comes with a lid featuring a feeding door for convenient access without fully opening the tank. The included LED light is bright enough to support live plants, and the filter, while having a somewhat strong current, appears sufficient for the inhabitants.

The tank also boasts a built-in LED light which is ideal for live plants, and the filter is working perfectly for my needs. The inclusion of a filter and light is a huge plus, saving you the cost and hassle of buying them separately. Overall, setup was straightforward and very user-friendly. The attractive design seamlessly integrates with any home decor.
I purchased mine from PetSmart for $35 (on sale; usually $50), making it a cost-effective choice. The tank's dimensions are not specified in the review but appear suitable for two betta fish.
Betta Fish Care and Tank Mates
My betta Luna, who had been in a cramped one-gallon tank, is thriving in her new 2.5-gallon space. After a week in the larger tank, she shows significant improvement in activity and color. The extra space and better environment have made a positive difference in her health and well-being. It’s crucial to note that betta fish need at least 2.5 gallons of space; smaller tanks are detrimental to their health.

Comet, my new betta, is also very active and vibrant in his new home. His fins are full and colorful, demonstrating his happiness in the spacious environment. The larger tank clearly contributes to their overall well-being compared to the smaller tanks I previously used.

Turbo, my mystery snail, is also enjoying the upgraded living conditions and happily explores his new larger space. I even gave him a cucumber, which he quickly devoured. He has been active since being introduced to the tank.

Tank Decorations and Plants
Luna's side of the tank features a golden elephant decoration, a stem plant, and a marimo moss ball. I love the quirky and creative touch of these accessories.

Comet’s side includes two A-named plants (names not remembered fully) and rocks collected from a North Carolina trip. The simplicity of this side balances well with the decorative elements in Luna’s side.

The substrate used is white sand on both sides. While the divider has a small crack allowing some visual contact between the bettas, this has resulted in some flaring, particularly from Luna initially. This however, seems to be diminishing over time.

Conclusion: Is the Top Fin 5 Gallon Divided Betta Tank Worth It?
Overall, the Top Fin 5-gallon divided betta tank offers excellent value for its price, providing a spacious and well-equipped home for two betta fish. The inclusion of a filter and light is a great advantage. The only minor downside is the slight crack in the divider that leads to some initial flaring, though this appears to be resolving itself over time.

The tank's design and features contribute greatly to the betta's happiness and health, allowing for visible improvements in activity levels and color vibrancy. This tank size is essential for betta well-being, avoiding the problems of smaller tanks.
The tank provides a comfortable and stimulating environment for your betta, with room for customization through decorations and plants. While minor adjustments are always possible, the tank itself stands as an exceptional choice for responsible betta fish keeping.
