My male betta of around 3 years has recently started acting sick and lethargic. His scales around his head and gills are raised and his gills seem swollen and are sticking out some. His fins are droopy and he is sleeping almost vertically, with his head pointing upwards. He is still eating some and at times will swim around actively still.
I first noticed his being kind of vertical on Tuesday and thought maybe he just had constipation or something so I didn't feed him for a day and Wednesday morning I gave him a little bit of a pea after doing some research on here. That is when I noticed that some of his scales were starting to raise up and that his gills seemed somewhat swollen. Wednesday night I checked on him and gills were very swollen and sticking out a lot so I started him on Maracyn II thinking it was the start of an infection since the water at my apartment is so bad and his tank not having a filter.
Now his scales are sticking out a good deal as well though, which has me more worried after doing research and seeing dropsy pop up a lot with these symptoms. I haven't noticed any bloating on him yet, but it is a little hard to tell with how swollen his gills are.
I know that his current tank is on the small size for a betta and I have been doing a fish-less cycle of a larger tank with RO water for him that has a filter, I am just afraid to move him to it now that he is showing symptoms of being sick. Would it be best to wait until he gets better to try and move him to a new tank? Or would the new tank with the filter help?
I am a little worried that it may be the starting stages of dropsy, but am not sure and would like any feedback.
