He is an African lungfish, I have had him for 7 years and when I got him he was full grown, I am guessing he is probably around 10-12 years old. He is about 28-30 inches long. He lives in a 200 gallon tank that was built for him. The nitrites were high so i cleaned the tank and kept doing water changes ph and all were normal. He stopped eating fish about 2 years ago, he loved koi stixs and always ate them, I tried all diferent types of food, but not into anything but the koi stixs and dog food
kibble. But before that he would eat anything. I am afraid to go to my shop this morning as I think he might have died.
