Features:

• THE PERFECT AQUARIUM FOR SMALL SPACES — The HALO aquarium's design is inspired by the simple beauty of a classic fishbowl, but with a twist. The hidden waterline and 360-degree view give the appearance your underwater world is floating in your room. The 4-gallon tank's compact size is ideal for desktop or tabletop display.
• DURABLE CONSTRUCTION — biOrb aquariums are made from acrylic, which is 10 times stronger, 50% lighter, and 23% clearer than ordinary glass aquariums. Acrylic is also a good insulator, so you don't lose as much heat as you would with a glass aquarium.
• PATENTED FILTRATION SYSTEM IS EASY TO MAINTAIN — All biOrb aquariums have a true 5-stage filtration system including biological, mechanical, chemical, water stabilization and oxygenation that keeps it clean. The filter is conveniently located at the bottom of the aquarium, and the ceramic media surrounding it promotes the growth of beneficial bacteria.
• VIBRANT, MOOD-ENHANCING LIGHTING — Use the included remote control to select one of the 16 preset colors, fade through the entire spectrum of colors, and control the brightness of the LED lights. You can also set automatic 8-, 10-, 12- or 14-hour day and night cycles for a more natural scene for your aquarium inhabitants. This natural cycle helps cut down on algae blooms, which benefits fish health, water quality, and cuts down on routine maintenance.
• EVERYTHING YOU NEED TO GET STARTED, JUST ADD DECOR — Includes a 4-gallon (15 L) acrylic aquarium, multi-colored LED lighting with remote, a new quiet air pump, a low-voltage 12V transformer, filter, air stone, ceramic media, starter water treatments, and instructions. Just add decorations! Also includes a 2-year warranty.
