Spacious Upgrade for My Betta

I recently upgraded my betta fish Sparky to this 5 gallon TopFin tank after he outgrew his 2.5 gallon tank, and I’m really pleased with it! The size gives him plenty of room to swim around and I was able to add lots of live plants and hiding spots to make it feel like a natural environment.
The filter seems to have just the right flow rate – not too strong but keeps the water circulating well. My only minor complaint is that the aquarium light isn’t extremely bright, but it gets the job done. Overall, Sparky seems much happier and more active in his new roomy 5 gallon home. A great quality tank for the price.

Perfect 5 Gallon for a Single Betta

After lots of research, I decided to get this TopFin 5 gallon tank to house my new betta fish Calypso. It’s been the perfect starter size! The tank itself has a clean, minimalist look that fits in well on my desk.
Setting it up was easy, and I love that the filter provides good water circulation without being too turbulent for Calypso. I did decide not to use the plastic divider since I’m only keeping one betta. With some live plants and decorations added in, Calypso seems to be thriving in his new 5 gallon aquarium home.
For the affordable price and quality construction, I’d highly recommend this tank to anyone looking for an appropriately-sized home for their single betta fish!

Great Little 5 Gallon

This 5 gallon TopFin tank has been perfect for my betta fish Blade! It’s a nice compact size that fits nicely on my dresser, but provides ample swimming space compared to Blade’s old 2.5 gallon.
The low-flow filter seems just right – creating decent water circulation without pushing Blade around too much. Adding a heater and some live plants made it into a nice customized little aquarium environment that Blade really seems to enjoy exploring.
My only very minor gripes are that the light is a bit dimmer than I’d prefer, and the tank can be a little tricky to disconnect the light/filter unit for water changes. But those are pretty insignificant issues. Overall I’m extremely happy with this quality 5 gallon tank for my betta!
