WANTED: Small koi

ISO free small koi to restock a pond from chlorine toxicity. We did a water change the Tuesday before the 4th and didnt know that the water company started to add chlorine to our water. We lost all of our koi and two fish tanks worth in the house. We figured it out and treated the water. Now, we need to restock. We are not looking for anything special. Just need some life back in our pond. Butterflies would be nice. We are in North Texas area 75424. Thanks for your consideration.
