You didn't give the age of the tank in your question.

Sounds like a mini-cycle going on. Your nitrites are the giveaway.

Do several partial water changes over the next week.


Sorry..This tank is about six weeks old, it had a fast cycle using
Bio-Spira and mollies...

The water hasn't changed hardly at all untill sometime between
Thursday morning and Sunday morning. This one fish is the only one
acting wierd. Water was topped off Sunday evening... about 2 gallons
in the 45G tank.

Since he is the only one acting funky, the Otto is fine, the Angel
fish are happy, and everyones colors all look good, I was suspecting
something else....

I'll be checking water over the next few days....

TIA

You might have introduced something nasty to the tank. Clown loaches are
all wild caught, so it's not uncommon for them to bring in all sorts of
bugs, skin & gill flukes, new bacteria's etc. Quarantining the Swordtail
might remove most of the contagion (ie: gill flukes), and then decide if
you want to treat him if there is no sign of improvement, or right away.
He might improve on his own in the community tank. It just depends on
what it is. Different fish species have different susceptibilities, so
they rarely all get sick at the same time to anything. If you had other
livebearers, they would be next in line. There is even a product called
Livebearer just to kill flukes in Livebearers.
