I have had them for about 3 months now but I'll be honest, I bought these two babies from Walmart. They were the only long tailed koi in the tank so after watching them for 20 minutes I bought them. Well I realized I have no idea what kind they really are after watching the show Tanked where they did a huge koi pond and none of them looked like my two babies. Well I just took the best pictures I could of them in hopes someone can help me out. I named the gold one Disaster and the silver one Tranquility.
