Gold fish care
My coworker bright gold fish . Her daughter had some kind of project in school , which i hate. They tried to see how long fish can survive. So she was fine for a few days, she ate and was active.
I have 8 bettas , i never had any other fish so i thought that i have to do just what i do for bettas. Change the water put drops...She was fine for one day and then she looked like she don't have enough air. She was on the all day long and open her mouth..now she don't eat and on the bottom.
She is in one gall . She lived through Friday- Monday. But she looks like she is dying.
How can i help her? Does she has lock of the oxygen? Please don't tell me i need bigger tank, fish on my table at work. I can't take her home.
