How to Provide Good Tank Conditions for Optimal Growth of Goldfish

Goldfish can increase its body length by as much as 50% in the first 7 days, but these rates are totally dependent on the type of food and aquarium conditions.

Goldfish are predominantly lovers of fresh water. Even though they may tolerate hard and soft water, they will not tolerate water that contains high ammonia or high pH, neither will they tolerate water with extremely low dissolved Oxygen, especially that caused by pollution.

Frequent water changes are required to raise goldfish in tanks. Due to their extensive growth, which can reach 14 inches, these fishes must be kept inside a tank of sizes of up to 50 gallons. You need to change as much as 20% of tank water on a daily basis.

If you keep fries in crowded conditions, you may have to replace as much as 30% of the water on a daily basis. Goldfish is known to produce hormones that can inhibit its growth and that is the reason why most people believe that goldfish will only grow to the size of its container.

The build-up of certain hormones by goldfish will affect the growth of tank mates, hence you need to replace tank water as frequently as you can.

It is also important that you provide sufficient space or add filtration. Goldfish will require up to 24 sq. Inches of filtration. This will provide enough Oxygen for the fish to process the food needed for optimal growth.

While water temperature of 24 C degree is needed to hatch the eggs and maintain optimal growth of Goldfish into the adult stage, some species may require slightly higher temperatures to keep their scales and color changes.

You must avoid placing your aquarium directly in the position of the sun to avoid excessive heating of the water. Though you do not need to cover the tank with a shade, a darker and quieter area of the home is much more preferred.

Goldfish is known for its huge appetite, the fry, for instance, will eat an equivalent amount of its body weight in a day. The fry or young goldfish must be fed live food containing a sufficient amount of protein daily and this can be supplemented with prepared meals after the first 5 weeks.

Goldfish must be kept at optimal health. Fishes that are smaller than 2-inches in length are susceptible to a wide range of parasites including the body flukes and gill flukes. These parasitic infections will either kill the goldfish or slow down its growth.

If you are starting with the fries, then you need to ensure they are fed twice daily and give them sufficient food that can last for at least an hour. Giving goldfish too much food can make them exceed their average growth length. Brine shrimp is one of the best natural foods for goldfish.

Conclusion

In conclusion, the goldfish is a freshwater fish and it is one of the most commonly reared fishes in aquariums in homes. Though goldfish can be kept in tanks and reared by beginners and experts alike, they must be taken care of just like any other fish reared inside a tank.

The only way you can help the goldfish to attain its optimal growth rate is to ensure the right tank conditions, most especially the water pH.

You should know that your goldfish is becoming uncomfortable when it starts rubbing its body against some components in the tank.

For instance, a goldfish may rob its fin against the rock and plant when the pH is shooting pass 8.5. The only way to avoid this issue is to change at least 25-30% of the tank water on a daily basis.

In addition to replacing the water frequently, dead matter, including plants and wood must be removed immediately they are sighted because they contribute to higher pH levels.

You may want to limit the feeding of Goldfish to twice a day to avoid food remnants from lowering or raising the pH levels of water excessively.

Make sure you keep a tank mate of the same size as your goldfish, a more aggressive and bigger tank mate may kill your goldfish by mistakenly seeing it as food.

Goldfish are upward swimmers, in as much as they enjoy moving around water plants, they must be provided with sufficient Oxygen.
