I'm always looking for unique fish tanks, and really like the AquaVista 500 wall aquarium from AquaVista.

With many wall aquariums, you'll find inadequate filtration, and difficulty heating, cleaning, and maintaining the tank.  AquaVista solves that by including both an under gravel filter and a biological wet/dry filtration system.

The tank is also equipped with a lighting system that is bright and vibrant, and an air pump to keep your water oxygenated.

On the side of the AquaVista 500 is a programmable controller with keypad and lcd screen.  Heating levels are easily programmed in.

While all those necessary features make this one of the best designed wall aquariums out there, AquaVista added more value to this beautiful tank.

How would you like to have easily changeable backgrounds and interchangeable frames?  Well you can.  How cool is that!

Take a look at this video review of the AquaVista 500 wall aquarium, and then check out their other wall aquarium below; the Panoramic Wall Aquarium.

AquaVista also offers a Panoramic Wall Aquarium.

This fish tank would look great above a fireplace or couch!

Like the AquaVista 500, the Panoramic Wall Aquarium is full of the necessary features.  It includes a double filtration system, which is nice with the larger size, lighting, air pump, and heating controlled by the programmable controller.

But then AquaVista again adds more value with a carbon dioxide infusion system, which is perfect for helping maintain live aquarium plants.

Also included is an automatic fish feeder!

Available in 5 or 6 feet lengths, the AquaVista Panoramic Wall Aquarium is a great conversation piece.

I'm pretty impressed with what AquaVista has done.  It's not surprising they have over eight patents out, issued or pending, for their designs.

Scavenging for food in the gravel, Soumyakundu's Rainbow Shark is a beautiful example of the Epalzeorhynchos frenatum species. A member of the Cyprinidae family, this fish is commonly stocked in the freshwater community fish tank.

The rainbow sharks blackish-green body is accented by colorful reddish-orange fins. Also known as the Red-finned Shark, or Ruby Shark, this fish is primarily a bottom, and mid-level dweller. They're happy eating most anything. Spinach, lettuce, tubifex worms, algae, and leftover fish food, make them happy.

The Rainbow Shark is a semi-aggressive fish, which can also be very territorial. It's suggested you have just one in the tank, and fish in similar size. Also, it's best to avoid combining the Rainbow Shark with other freshwater sharks, such as the Red-Tailed Shark and Black Shark. Here are a few more characteristics to consider:

• Grows to 6 inches
• Tank parameters: 73-80 F; pH 6.5-7.5; KH 10-15
• Minimum tank size is 30 gallons; 50 gallons preferred
• Requires moderate care
• The rainbow shark is an Omnivore

Rainbow sharks are compatible with most barbs, danios, loaches, plecostomus, and the gourami. You just have to make sure and leave them space to establish a territory.

Breeding the rainbow shark in an aquarium setting isn't done due to the sharks aggressive behavior. If you've got the room in your fish tank, and proper companions, the rainbow shark can be a fun fish to keep.
