Recently I moved my crowntail betta, Rocket, from his spacious 3 gallon tank to a small 1 gallon tank until I can buy a new 3 gallon tank or get the accessories for the old one fixed (bubbler stopped working).
I have had Rocket for a year now and he has always been happy and healthy.
I came home from work today and went straight to his tank, as I always do. When I turned the light on to his tank he didn't start swimming around fastly as he usually does (which is how he got the name Rocket). Instead he just kind of stayed near the bottom and wasn't moving much. I moved my finger by his tank and only then did he start swimming around. I noticed that he had some feces hanging from his abdomen area and he was very very enlarged. I immediately researched betta diseases online and came to the sad conclusion that he could possibly have Dropsy.
However, the description of Dropsy didn't mention anything about feces. He still swims around his tank like normal if provoked by my finger (but only when provoked now instead of swimming around all the time as he usually did) and his appetite is still as usual. His tank is always clean and he has never had a problem until now.
So what I'm wondering is, is it too late to save him?? I'll be honest, this is my first betta. Could I have caused this by switching him from his 3 gal to a 1 gal?
Has anyone ever saved their betta from Dropsy? How do I go about treating this disease?
