Penn Plax Radius Curved Corner Glass Aquarium Kit Our Penn Plax Radius Curved Corner Glass Aquarium Kit contains what you would need to get started on your own aquarium fish tank. It features a unique "bent glass" frameless design that will look sleek and fit seamlessly into your home. Typical aquariums are built using 5 pieces of glass glued together, whereas our tanks are only 3 pieces which provides increased strength and quality through fewer glue points and seams. It contains rounded corners that provide superior visibility from all angles. The Penn Plax Radius Curved Corner Glass Aquarium Kit is available in a variety of sizes to accommodate your aquatic interests and needs. The smaller varieties are ideal for use as a Betta fish tank while the larger kits are great for housing small types of fish like guppies, rasboras, cory cats, dwarf gouramis, platies, and more. Simply fill this desktop fish tank with the décor of your choosing (not included in kit), and remember to let the system stabilize before adding fish (it"s recommended that you set up your aquarium completely and let the filter run for at least 24 hours before adding fish). The Penn Plax Radius Curved Corner Glass Aquarium Kit includes the following items: 5 and 7.5 gallon kits: Aquarium with plastic, hinge-style lidUL-Approved Cascade 300 internal filter (filters 70 gallons per hour)10 LED clip-on light
