Which types of goldfish should I get?

So as you've seen on my last thread, I decided to get 2 fancy goldfish instead of a blood parrot cichlid. The only question left:

What two types of fancy goldfish should I get?

I preferably do not want the same type of fancy goldfish, but I know the options are limited because each fancy has a different "disability" that they might get bullied over.

Orandas were on my list, but I heard they get too big for a 29? If someone could clarify this, that would be very helpful.

 

I wouldn’t assume that a large breed goldfish won’t get large; my ryukin sure surprised me. I would not keep an oranda or ryukin with another goldfish in a 29. That’s a LOT of work, and if they get big, you’ll need to upsize.

I would keep 2 fantails or a fantail and a nymph (single-tailed fantail). If you want more variety, maybe a telescope/moor, but they can get kind of big.
