6th Starfire 50-Gallon Rimless Aquarium

Specifications

  • Dimensions: 24 x 24 x 20 inches
  • Weight: N/A
  • Material: Glass
  • Color: Black
  • Shape: Square

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.

Pros: 

  • the best glass quality you can get;
  • amazing support;
  • quality plumbing included for the overflow.
