What's wrong with my neon? Swollen belly.

[Zoidar]

My black neon tetra has a swollen belly. This has happened two times before and only to my female black neons. I thought it was constipation, but now I don't know

Little more information would be helpful what are your water parameters ammonia nitrite nitrate pH temperature the other neons who had the swollen belly did they get better could be egg bound something else could be going on internally if it were egg bound you would want to do Epsom salt baths 1 table spoon for 1 gallon for no more than 15 minutes for 5 days as Epsom salt acts as a muscle relaxant@Zoidar

At least one of them died. 

Ammonia = 0mg/l

Nitrite = <0,3mg/l

Nitrate = 1mg/l

Ph = 7,2

Temp = 26°C

I have to add this is not a new tank, had it for 3 years.

The fact that your seeing nitrite could mean your tank has had a interruption in the cycle what I would is test daily if you see any nitrite do a water change and add a double prime or Fritz complete to help detoxify any nitrite first I would do the Epsom salt baths for 5 days if your not seeing any improvement after 5 days them I would do a course of metroplex in food feeding a small amount twice a day for upto 3 weeks @Zoidar

<0,3 nitrite is the lowest with my testkit.

So it could be 0-0.3 I would just follow the treatment I  recommended

Yeah! Ok, thanks for advice!

I tried Epsom salt. As you can see the fish has slimmed down, actually after only one treatment. She is swimming slantwise, but looks much better. I hope she will recuperate completely. Thanks!
