Problem with NTT

[Darwin]

I have a couple of NTT in a 400 gal with other fish. All the other fish are fine.
Ammonia = 0
Nitrate 15-20 ppm
Temp 82 F

For the past couple of days the smaller of the two NTT has had a bloated abdomen. Looks like it over eat, but it has not eaten much. Now the fish is much more lethargic and swimming / drifting in a head down position.

Any advice? Swim bladder problem? Does not seem to be overly buoyant more constipated?

Thanks

Not sure, It could be swim bladder. I'm sure someone with more knowledge can help

Maybe try feeding it peas or something

SBD. Peas, epsom salt, major water change (nitrates can cause this), lights off to reduce stress... I think Lupin wrote an article on it somewhere in the illness and health section.

Thanks for the direction, I read Lupin's summary of SBD.

I put in a drip system 6 months ago to manage the nitrates and for the most part they have beem below 20 ppm.
