The Arapaima is a tropical fish of the Amazon basin. It is one of the largest freshwater fish in the world. Arapaima reach sizes of up to 15 feet in length. The scales are olive-green, turning increasingly reddish towards the tail region.
The swim bladder is open to the pharynx and the arapaima uses the bladder which is rich in blood vessels as a lung. Arapaima feed mainly on fish.
This one is now 46 inches and growing! I had it for one year. I bought it at 15 inches. That's 31 inches in a year!! The tank it's in right now is 720 gallon with a 80 gallon wet/dry filter, mechanical carbon filtration, and titanium system heater. With center overflow. Total gallon is 800 gallon! Dem:(8'L X 4'H X 3W')Made of best quality 1 inch thick Acrylic, by Sea Clear all around!! It looks like the tank is too small for it right now. My next project is to build it a 1500 gallon indoor pond. I'm thinking about selling the tank for $6,000.00. If anyone is interested please let me know. I Live in Los Angeles CA. Thank you Enjoy!!
