Hello all....I have a teenage Tiger Oscar and an adult Jaguar. For the past 5 days, I noticed that the Jag was lying on his side and not eating. Every once in a while he would chase some of the other fish around for a minute or two and then go and lie down again. Today, I'm noticing that he's REALLY lying on his side FLAT. I saw that he was scratching himself on the rocks so I treated the tank for 3 days with quick cure and then did a 75% water change. Today the Oscar is doing the same thing. I don't know what's wrong with them. Do they have dropsy? I really don't want to lose these two. Can anybody diagnose what's wrong and then suggest the proper meds for them?
