KOI FISH VS GOLDFISH THINGS TO KNOW BEFORE YOU BUY

I bought what I thought was a Koi betta - mainly white with a small amount of red and black. He has completely transformed shades, and now he is mostly blue and black!Rather typically just in that timeframe, the fish experienced adjusted from when I'd found and acquired it. So if you don't need it to change, keep away from marble bettas (aka koi).
