Mixing fish together in the aquarium can be one of the biggest challenges faced by the hobbyist, especially in aquariums 200 liters and smaller, which is what most of us are dealing with.

Many times a hobbyist brings a fish home, a fish which "the guy at the pet shop said would mix ok", only to find that this fish doesn't get along at all with another fish in the aquarium. Learning to predict these situations before they happen often can only come with experience. Hopefully I can point out some things to consider and some things to avoid, when looking to develop a community of fish in a small glass box.

One thing you have to understand is that fish behave instinctively. You can not "train" a fish to get along with another fish. Fish instinctively are concerned with 2 things: feeding and breeding. When you add a new fish to an aquarium, the established fish now have competition for attracting a mate and for establishing a territory from which to feed. For many fish this "territory" can be the entire aquarium.

Goldfish Need A Colder Tank Than Tropical Fish

by hdhnterpaul

So you can't keep them both in the same tank.
Plus, as was said, the gold fish will easily outgrow a small tank and even a moderately large tank will only hold so many gold fish once they grow as large as they do.
Eight to ten inches is not unusual for a common goldfish.
I'd suggest a twenty to thirty gallon freshwater tropical fish 'community aquarium' consisting of 'live bearers' such as guppies, platys and swordtails. These fish are easiest to keep.
No, it should not be expected you will lose a few fish at the beginning- that is a typical Petco employee for you
