Help!! Goldfish Emergency!!

my goldfish is laying at the bottom of his tank and just moving his mouth! He was fine yesterday and I woke To him being ill. ): what do I do?!

 

What are the parameters of the water?
What size is the tank?
How many other fish are with this one?

 

Seems some serious problem with water parameters , you can change 30-40% water and add seachem stress guard ...

Oh and do not net the fish or disturb it too much , the shock might be too much for it to handle

It’s a 30 gal, he is alone , and I’m going to do the parameters now, although I tested it two nights ago and it was all normal ): there is a small algae bloom in the tank but I don’t think that hurts the fish , right?

 

What kind of goldfish? Fancy or single tailed? I agree with doing a large water change, unless your pipes were recently flushed/cleaned

 

I did a water change and ran to the store to get water conditioner and Ammonia reducer and came home and he was passed. ): I feel awful.

 

I'm so sorry for your loss

 

Oh my goodness!! I am soo sorry for the loss
