Hello, I have a serious question about my oscar. He has never been sick and I try to do everything to keep him healthy. He has an 130 gallon tank just for his own ass. I try to feed him high quality food and also put some multivitaminas on it when its possible, I also have taken a lot of photos last 2 years, so i can study his development. I have noticed that the sensory pits are totally normal, and when the oscar grows these sensory clusters are also growing (not the pits) But i have also noticed that the area under the nose is a little bit eroded (Does not looks like HLLE). It started a year ago, and these light grey spots have also grown a little bit. Has this something to do with HLLE or is it totally normal. Because I have noticed that a lot of grown up oscars have this decolouring under the nose. Because i cant find information about this fact. And now i am a bit insecure about the reason. May be it has something to do with the quick growing process or ??? Please i need to know because this fish is like a brother to me
