Pretty sure my betta has dropsy :(

HI guys!

I went on my honeymoon this past week and came home to find my betta with a super swollen stomach. My friend had been staying in the house and was feeding him the same way I do. I don't know what went wrong. There were seven emerald eye rasboras in the same tank - all of them seem to be fine. They were all in a 10 gallon tank. I read online that I should quarantine the betta. So I moved him into my 3 gallon tank that I previously had empty. I used some of the filter materials from the 10 gallon in the 3 gallon hoping that will cycle the 3 gallon. But I'm planning to change the water daily anyway. I also read to dose the tank with aquarium salt. I've done this to both tanks. I also put apI general cure into the 3 gallon. Anything else I can do to help him?

Thanks in advance!

 

Have you tried a shelled pea? He may be constipated.

 

is the (10 gal) tank cycled? what are the parameters? temp?
can you get a picture of your betta?

The 10g's tank parameters are pH: 7.6, Ammonia: 0, Nitrites 0, Nitrates (high): about 40.

The 10 gallon tank is cycled

The 10g's temperature is 78.

 

Thinking about it more, I think it's constipation. The nitrates are really high (they are normally around 10). I think my friend just overfed him. So I gave him an epson salt bath and I'm fasting him for 2-3 days. Any other tips?

 

A shelled pea. It will help his constipation if he has it

 

yes, I'd do what tokiodreamy said, feed him some shelled pea, and then fast for 2-3 days and see how he looks
