As a koi owner, it is crucial that you keep your koi's tank or pond at a reasonable temperature. Koi rely on the water temperature to assist with their digestive process and cannot digest food if the water gets too cold.
Report Abuse. You need a pretty large tank for koi, at least 100+ gallons. It would be best for larger, like 500 gallons. Most people who keep koi keep them in a pond, where they say 1,000 gallons for one, and 100 gallons for every added. Instead of koi i would get either goldfish (they can get pretty big and be beautiful) or tropical fish. Goldfish need at least 30 gallons for 1, and 10 gallons for every extra one. Tropical fish can be small and only need 5 gallons(such as tetra's) or large and needing 30+ gallons.
