Nervous Goldfish

[suby7272]

Hi guys
I have two goldfish (i dont know the name of their kind) in a 20g tank, and today I noticed them acting very nervously - just zipping from end to the other. I dont see anyother fish harassing them as well - except for solitary Tiger Loach who simply want to come closer to them - with no bad intentions.
I am worried, please help.

Regards

Suhaib

are all of your water conditions the same/ok?

check your water condition, your ph must between 7 - 7.5,
and temperature around 75 - 82 Deg F.
Suddenly temperature and PH change can make your fish become stress.
I hope these step can help you :

1. IF your PH below 7, add salt to raise it, if your PH too high, change the water 50% .
2. use heater to stabilize temperature
3. turn off the light
4. stop feed the fish until they get better.
5. separate the tiger loach with the goldfish.

Actually, I believe 70-75 is a more appropriate temperature for goldfish
