Midnyt died! (My goldfish)

i changed Treasure's water yesterday afternoon... that's when i got these readings
 
she's in my 10gal. I left them 2 there alone cuz I wanted some fry :D
 
Move her to the 30 then...that is the best thing for her and will make it easier to take care of her in the long run.
 
ok. can i put some fantails in there with her?
 
I'd recommend against it. She's a more competitive feeder than fancier strains of goldfish, so they wouldn't get enough to eat. Also, a 30 is the minimum for a single goldie, so putting more than one in that sized tank wouldn't be prudent.
 
yea, you're right. (as always lol!) :)
 
thank you for your help! Bye now!:)
