Review on Enhance Your Environment with Koller Products 3.5-Gallon Aquarium: Sleep Sound Machine, LED Lighting, and Power Filter by Erin Wright

Consider how much this aquarium costs and yes, for the price I think it's worth it. This is a good starter tank to see if you want to go ahead or buy a bigger tank and really spend some money on a 50-200 gallon tank. The filtration system is not very good (again $), the water gets cloudy just after cleaning the tank and releasing the fish. Artificial planting and gravel are also NOT supplied with this aquarium (note the short sentence in the product description).
