About 2 weeks ago I bought a new tiger oscar from a local store. I fell in love with it because they had a selection of larger ones. This one is about 5 or 6 inches long. I also loved the color of it . Right after I put it in the tank I noticed it was missing some scales on both side of it's body. I call the store, and they said that is normal since it was in the tank with other Oscars, and it should be fine. After reading more post, and viewing several pictures I have discovered that this Oscar has Hole In The Head disease. When I saw the picture I knew that mine had it. I went to the store with a picture, and they said that Hole In The Head Disease is just an Oscar thing, and it will go away, and the fish will be fine. I have one day left on their return policy, and I am leaning towards taking him back for a refund. When I was in the store I noticedI most of the larger ones they had in stock had this.
