This video looks at how big of a tank you need to house your goldfish. This is meant to be used as a general guideline.
- I keep my two (5-7 inch) orandas in a 40 gallon (150 liter) tank. - The more room you provide your fish, the healthier it will be and the more it will grow. - Small, overstocked tanks lead to stunting and toxic water which can kill your fish and stop them from growing to their full potential. - Under no circumstance should a goldfish be kept in a bowl.
Basic stocking guideline = 10 gallons (40 liters) per fish - This guideline is good for young fish. You will eventually need to upgrade your tank as your fish grow to adult size.
Stocking Fancy goldfish = 20 gallons (80 liters) for the first fish and 10 gallons (40 liters) for each fish after that
Stocking single tail goldfish = 20 gallons (80 liters) per fish
