I have three baloon rams, two are about three months old one about five months. I used to have another but it got hole in the head and died. The 5 m one now has hih and is slowly getting worse. Last night one of the others was looking odd. He lost all his colour and was hiding at the bottom of the tank. After feeding he swam to the top of the tank and just lay at the top with his mouth out of the water. When I got home tonight he was on the bottom on his side. He went from a vibrant orange to albino white in less than 24 hours. He had no injuries visible or fungus ich etc. I hospitalized him but it was too late. Now the one with hih is at the top of the tank, but his color has gone brighter instead of fading out. He's eating but acting really lathargic. I kind of expect him to die because of the hih but I didn't want to give up hope. All other fish are okay and happy. What could make them do this? no2 is 0 , amonia is 0. no3 is 7 . Theres not much info on baloon rams out there and the guys at the LFS say that these fish should not even be able to get hih, so I'm at a complete loss. They're my favorite fish
