Hello! Welcome to the guild (:
I'd like to point out that common goldfish grow
really quickly and they'll be way too big for 10 gallons before long. Unless most of them die first, that is. xD;
They'll be gaining inches in no time, so if you want them to survive you should probably plan on finding extra accommodations for them.
So, how long have you been interested in fish? Is this your first experience with fishkeeping?
smile If it is, I'd like to recommend a great website with tips for caring for you goldfish. It's called
Koko`s Goldfish World.
It's one of the first sites I relied on when I first started out with goldfish keeping a couple of years ago. It's super handy to keep on bookmarks/favorites.
Anyway, I'm looking forward to any pictures of your tank you might post in the future! (:
