My betta fish started acting funny about 3 weeks ago,
Just floating in the top corner of his tank, not eating, and swimming occasionally on his side. At first I though it was swim bladder so I fasted him for a few days.
Now his head is a going white from his lips down compared to its usual deep red. Also when he is breathing quite fast and you can see it all white under his gills when he lifts his head up. His body is starting to go bronze and sometimes he just goes crazy and attacks the side of the bowl. His find are fine.
I tried treating him once with a protozoan medication and have just repeated it.
His tank is over half a gallon and he has a silk plant. He also has a small heater and his temperature is usually 24degrees Celsius. His water is clean and conditioned, I've scrubbed his tank out since he's been like this a few times as well! I also feed him betta pelets. Please help I hate seeing him like he's suffering, what should I do?!
