Can you post the exact numbers from your tests please? How many fish are in the tank and how big is it? What's the temperature?

Hmm, well, your stats are fine...is it a male or female?

Not sure its not swimming around so cant see bottom fin if your thinking that its a female and its having babies it does not seem to be swollen at all

the aquarist will see a lot of this fish. They love to swim around and males love to display their intense colors, unless you have boisterous specimens or too small a tank. It is fine to keep multiple males in a tank because their "fighting" is mostly just a lot of fin flicking.

As its only in a 60L tank, this could be the problem you are facing.
