How to Clean a Goldfish Aquarium - Caring Pets.
Absolutely not! Goldfish produce alot of ammonia and put alot of toxins into the water. Good rule of thumb is 1 inch of fish to every 2-3 gallons of water with regular goldfish. For fancy goldfish.
Last Updated on 2020-02-02. Whether you’re new to keeping goldfish or you’re just looking to learn more about proper goldfish care, The Goldfish Tank is the ideal place to start. We give advice that will help you to understand your fish and their needs.
A 10-gallon tank is not appropriate for 1 goldfish, so three is ridiculous. Three goldfish will get the ammonia level super high, so I think the most likely answer is ammonia poisoning. Two other possibilities are overfeeding and disease. Fungus disease and ich are 2 likely possibilities.
Keep your goldfish in a fish tank no smaller than a 10 gallon (about 38 liter), and make sure that a minimum of 6 gallons (23 liters) of the space in that fish tank is dedicated to each goldfish (each goldfish should have 6-8 gallons or more (roughly 23-30 liters or more) space in the goldfish aquarium).
The general rule of one gallon per one inch of fish and the specific goldfish breed should be used to gauge the size of the tank. Common goldfish usually grow the largest, around 12 inches and more, under right conditions. If you are getting a pair of those, then you will need a tank of at least 40 Gallons.
Goldfish tank size requirements are different for different types of fish. The fish we call single tails are goldfish like Comet, Common, and Shubunkin but the Jikin and Wakin should also be included in this group since they also grow very large. These goldfish types more closely resemble the ancestor of the goldfish in size and body form.
