Pros: Plenty of good customer reviews, as most people seem satisfied with this product. Comes as a neutral white color that will work with any room’s decor, but you can also paint it however you want.
Cons: Some people have mentioned that it may be too small for a Beta fish, but others have also responded suggesting that it is fine if you do proper research on raising your Beta fish. When I first saw this product, I thought it was a cool little structure with separate rooms for your fish to go in and out of, apparently not. It is still cool though.
