37 gallon tank stocking

[Jt Lee]

Hi guys i am in desperate need of help, i recently bought my girlfriend and myself a brand new 37 gallon (140L) tank and i want to get some fish of my own, since my girlfriend has a 3 year old feeder gold fish, just looking for fish that are compatible and will be comfortable with our fish!

What kind of goldfish and how big?

Hi and welcome to the forum

Goldfish should only be kept with other goldfish. Keep fish that are similar sized and have the same type of tail (single tail or double tail). Do not mix single tailed fish with fantails (double tail) because the fantails get less food and can't swim as fast as the single tailed fish.
