I purchased several Koi for a future pond and kept them in a 5ft tank and they seemed to be doing ok, I came upon an 8 ft tank and decided to give them more space. Since there introducton they have lost their zest and spend most of the day hanging in the centre of the tank. Would it help to warm the water??
Help.
