I have a Blue Betta fish called Rico. Rico has been stuck at the bottom of the tank for several weeks now. It has not eaten for a while and it does not swim unless forced to. When it swims it is upside down or sideways and only for very short periods of time. He used to be a healthy eater and very playful and aware of everyone. His color has remained impecable, fins, scales and eyes look normal and there are no other signs of diseases.
His tank is small, about 1 1/2 gallons of water, I always use Water conditioner. Originally I thought Rico was suffering from swim bladder disease so after doing some reasearch I added salt and bettafix medication to try both the bacterial and constipation versions of the disease. I started that about 2 weeks ago. At that time I started to change the water every 2 days at first for 10 days but I saw no change and it seemed to bother Rico more so I stop doing that and still no change. I have not tried the peas solution since he does not seem to want to eat.
I feel bad for Rico and was wondering if he is suffering and what should I do next?
