2 fantails in a 37 gallon?

[Guest goldengoldfish]

Hi, I bought a 37 gallon tank today and I’ve been planning for fantail goldfish. Originally, I was only going to get one, but i was wondering if it is big enough for a pair. I really want to make sure they’re not crammed, and I don’t want to get two if it’s not big enough. Thanks!

Goldfish should have 20 gallons per fish. Also filtration is 10x the tank.
