We lost one of our Jumbo Tiger Oscars on Friday. We think from Hole in the Head Disease. We've had an ongoing battle with the disease for quite a few years. Tried everything imaginable. Do you think my surviving Oscar is lonely? Will he/she be okay by her/himself? I have a l50 gallon tank. I put feeder goldfish (6) in the tank trying to perk up the fish. I have (3) left and the surviving Oscar is not at all interested. He/she seems to be more active since the other one is gone.
