If you contact Petsmart right away they may take the goldies back. IDK what their return policy is, but with any FS it's best to ask them about it asap.
If you can avoid it, why get stuck with 10 goldfish you don't like, that will need 110g tank.
I'm not a fan of goldies either, they're to dirty for me. Plus there are so many
bright beautiful tropical fish, that goldies seem a little boring, IMO
. I mean no insult to those that are fans. It's all personal preferance and I prefer tropicals to cold water fish.
Anyway, if it were me, I'd call Petsmart first thing in the morning about returning the goldies.
Also given how dirty goldies are, and the fact that you have 10 of them, you should be doing 90% PWC
every day or 50% PWC
every 12 hours. Every 12 will be less stressful on the fish.
Good Luck with your new tank, getting it cycled and getting rid of 10 goldfish.
