DO NOT EVER RELEASE IT INTO THE WILD.
Besides, you have a tiny fish living in a tank...you think releasing it when it is larger will mean it will survive? It never had to "live" wild. I suspect most will die in this scenario, having never learned to survive in the real world.
PLEASE do not ever return it...that would be downright irresponsible.
Please RESEARCH good fish and inverts before bringing them home, as you have, IMO, a responsibility to kill these animals. The introduction of foreign species - whether fish, inverts or pathogens - is a serious topic. And aquarium hobbyists get A LOT of the blame for this destructive behavior.
Please do not do it.
Just like I was saying in the thread mentioned. If you are willing to take on local critters in your tank, keep it all local. If not, then dispose of or trade fish that you don't keep with someone you know.
My small coral 15 tank is the first one I have had in the last 20 years that has livestock that I actually paid for. And all my corals are frags from other tanks.
