Does this fish have dropsy

[FishSupreme]

The first fish is in a quarantine tank. He’s being treated currently with aquarium salt. 1 taboo for every 3 gallons. However today I had ammonia at 0.25. My tank was doing well for the first week (I tested and everything was fine) but he’s half blind so some food started to rot. I did a 50% water change so everything is now 0 ammonia and 0 nitrites. The other pictures are of an established aquarium. It’s been cycled for over a year now. The fish in concern is acting normal. Though both of the remaining goldfish hide they’ll come out for food. His appetite is intact and he seems fine. I’m just worried his belly is starting to bloat perhaps. Ammonia is 0 but I also did my weekly 50% water change today. Thankfully no scales are pooping out. His food seems fine. I think the thing on his head is a tumor. Sorry for posting so late. If I need to add the emergency template please let me know.

Hmm. It's hard to tell from the pictures but I don't think so. He could just be a little chunky? Or maybe he could be female? I'm not sure. I'm not a goldfish person. Hopefully, someone else can give your fish a better diagnosis.

I do not see anything to suspect dropsy.

Thanks! I‘be been fortunate not to have to deal with dropsy. From what I’ve seen there is no apparent pine coning . I’ll continue to monitor behavior but I think he’s fine.
