"I bought this tank as a step up from a Betta-specific tank to help my single male thrive. I've had it about a month and a half now and he's doing great. Some say that the filter is too strong for a Betta, but mine loves getting his exercise by swimming against it and then diving to rest. It's large enough to have a small heater to keep him at optimum temperature and support a variety of decorations. I fit two plants, a hollow chest, and two solid items in there and he likes to sleep/hide in and lay on his accessories.
He came down with fin rot and I treated him for it, but realized that the Bio-Wheel bacteria could have been killed by the medication I was giving. I waited a couple weeks to see if the wheel showed any change and learned that the beneficial bacteria on the wheel are more resilient than I thought and were thriving, even after a week of antibiotics.
If you're looking for an excellent tank for a lone Betta, I highly recommend this tank."
