Here is my pond with the koi I purchased. Would these guys be too small to spawn from what you can see? Fish are toward the bottom right.Sorry I didn't get back to you on that. I have had several customers want to buy every fish I had- resellers! Others that say they have ponds but have aquariums. People that want a 20" koi to put in a 300 gallon pond! I sold 4 fish to a man who told me he was in the process of building his pond. Saw the fish on Craigslist the following year in a 55 gallon aquarium, bent spines from crowding! My fish now go to people who can prove that they can care for them.
