7th Starfire 50-Gallon Rimless Aquarium

Starfire Aquariums are a USA based manufacturer offering quality fish tanks with unbeatable glass clarity unseen in competitor products. This is a great Starfire 50-gallon tank that almost looks like a cube, measuring 24β€³ L x 24β€³ W x 20β€³ H. This is excellent for someone who wants to house a lot of fish with limited room space. This tank is going to give you a unique look because of where the overflow is centered. Most tanks come with a corner overflow, but not this tank. Although, this tank is a great startup environment for your fish where a coral or saltwater environment would look stunning. Sadly it does not come with everything that you need as you would need to purchase a filter, pump, hood lamp, and a heater that are sold separately.

This is a designer tank and it is clearly constructed very well and provides a safe environment for your aquatic pets. Further details on this Starfire 50 Gallon Aquarium are available here, else learn about the aquarium material or manufacturer here.
