My fahaka puffer keeps going berserk

[Kgo890]

My fahaka puffer keeps on going berserk like he swim really fast and sometimes runs into the glass. I don’t know why my parameter are good. The only thing that looks like it helps is me turning off the lights but sometimes he will be fine in the light and then later he would do it again.


My water parameter
Nitrate no2 - 0 ppm
Nitrate no3 - 0 ppm
Ammonia - 0 ppm
Ph - 6.0

2.5 inch fahaka puffer
Water temp: 78
50 gallon tank

Your pH is very low. Lower than urine. What is it from the tap? Any tank mates? How did you cycle the tank?

Did a water change ph is now 7.2 and the still have the same problem. Only tank mates are ghost shrimp. It’s from stress but I don’t know from what

I need the rest of your parameters.
