Bottom Line

A self-cleaning tank that uses biological and physical filtration to keep your water clear and your fish happy.

Pros

Several layers of cotton filters remove impurities for improved fish health and to reduce odors. Kit has all you need to get started with a pump, an LED and cover, a filter and instructions. Use the app to adjust LED colors for a dramatic display. Small fish such as bettas, angelfish and goldfish will swim happily in this tank.

Cons

Replacement filters are hard to find. Same say tank holds less than the 4 to 5 gallons claimed.

Bottom Line

This compact aquarium uses gravity to create enough hydraulic pressure to flush out dirty water. The 1-gallon tank is made of impact-resistant plastic and looks great from any angle. An LED illuminates the tank in seven colors. Kit includes artificial plants, pebbles, a filter and a cover for the tank.

Cons

Some say self-cleaning process doesn't work well. Top isn't very secure.

Bottom Line

A versatile self-cleaning 5-gallon aquarium that your bettas will enjoy inhabiting.

Pros

A quiet filter system pulls water from the tank bottom and removes impurities. Each cotton filter lasts for from four to eight weeks. You can adjust the brightness and the color of the tank light. Bettas in particular like this aquarium but shrimp and small species of fish will also enjoy it.

Cons

Tank is not glass. A few users say kit's filter isn't strong enough to do a thorough cleaning.
