At a Hydrosphere Water Gardens, fish are our speciality. Our Japanese koi and goldfish are kept in a greenhouse in holding systems designed specifically for fish. In the greenhouse, koi receive natural sunlight which naturally enhances the koi’s colours and promotes health and vigor. The water quality is regularly tested and maintained at optimal levels by filtration systems designed for koi and goldfish. The water temperature is always within a few degrees of outdoor ponds (mimicking the seasonal variations in temperature), which means the fish you take home acclimate easily to your pond.
Avoid overcrowding your fish. Having too many fish in your pond can lead to poor water quality, resulting in illness and fish deaths

Koi and goldfish can survive in ponds over winter provided it is adequately deep to give them plenty of room under the ice and an opening is maintained in the ice to allow oxygen into the pond and carbon dioxide to escape.
