If you already have a cat, and you get a new kitten, and the cats fight... Do you stuff the new kitten in the freezer?
That's an abominable way to deal with pets... Pet stores know that these type of things happen. That's why you can almost ALWAYS take fish back. Even if they won't, almost always you can find somebody that can provide the gourami with a good home... It's not as if it's a difficult fish to care for, or requires some great expense to keep.
These are creatures that are completely at your mercy. I've been in a similar situation- had a kribensis who bullied and killed several of my fish, and it was a very frustrating situation... I found a store who was willing to take my krib, and give him an appropriate home.
I implore anyone facing this kind of situation to make EVERY EFFORT to find a home for a bothersome or incompatible fish, not simply take out anger irresponsibly on a defenseless animal who is only doing what animals do.
