I have a 75 gallon tank with a blue hippo that's about 2 to 3 inches long. She is losing color down the front and bottom edges it looks grayish. She eats really well and gets seaweed three times a week all my water parameters are in check my salinity stays at 1.024 and I do by weekly water changes. I don't know if it's from her scratching against the rocks but I wanna make sure she doesn't have a disease. Any help would be appreciated and I also know she will out grow my tank. thanks for your help
