So the gills of my Betta B.B. are red. But he is blue (and I have no idea what ammonia levels are just putting that out there.) He is recovering from dropsy and I'm worried about him. Background info: BB is a Walmart fish. He was a centerpiece at a banquet I took home (was not in good shape) so I got him a cute little tank and food. He has been doing great since then! I change his water frequently, feed him, and have a lamp during the day. He recently got a minor case of dropsy which he is recovering from. So I scrubbed his tank, changed gravel and water and cleaned his ornaments. I noticed for a few days his gills have been red. What does this mean? And how should I take care of dropsy better?
