I strongly recommend you do not release these or any out of area frogs in the wild. If animals can't handle the environment they will die . And if they become an ecological problem you could create a very expensive nightmare to your fish and wildlife department and even have local endemic species threatened . Hope the goldfish did predate them and they had no chance to become froglets and survive. Some animal sellers just want to make their $$ and will do anything to move their products, beware !
