Hello, I am new to forums and to fish.. I inherited an approximately 6 year old Oscar. He came to me in a 30 gallon tank. I replaced it with a 55 gallon tank to give him more space. I had a fish company set it up and they come monthly to clean it. He has had hole in the head for a long time per the original owner. He has been doing great in his new tank for the past couple of months. Now all of a sudden, he wont eat for 4 days. He loves to eat and always came to the top for feeding time. Now he seems uninterested. He was twitching a lot for the past couple of days. He is moving around more today and the twitching seems to have subsided. Today he seemed somewhat interested in eating but when I fed him, he ate it and it came out in many pieces out of his gills.. He tried over and over to eat it and it kept coming back out. I tried smaller pellets and the same thing happened. He seems like he wants to eat but isn't able to. Any thoughts? I am new to fish in general so anything that you think will help me, help him, please let me know! Pictures attached of his tank and Fred (the fish). Thank you!
