Bloated blackmoor goldfish sinking with lifted scales. Is it dropsy?

Updated On September 23rd, 2025

Hello I have a blackmoor goldfish that was showing signs of being bloated. He was floating at the top of the tank on his side and now has sunk. He has slow breathing and his scales are lifted a little bit but I'm not sure whether it's because of his arched position on his side or if it's dropsy. I have been adding antibacterial & antifungal for the past few days before his scales did that. But he isn't improving

Thanks for reaching out about Darwin and including photos. Unfortunately, medications added to the water rarely get absorbed systemically. This is likely a swim bladder infection, and systemic medications needed. A veterinary visit can assist with diagnostics and/or treatments. Injections of antibiotics are recommended. If dropsy is present, an aquatic veterinarian should be able to aspirate the fluid off, giving some temporary assistance while medications take effect. Check and correct water parameters and diet. Good luck.
