Ensure that all hard vegetable and fruits such as rice, carrots, and beans are finely chopped and well-cooked before they are given to the fish to eat.

It is better to feed your fish freeze-dried food rather than live as feeding live food to your fish comes with a slight risk of transferring diseases. Freeze food is not as good as live food but they offer many benefits without the same risk of disease.

Times of Feeding Goldfish

You must feed your Goldfish daily 1-2 times at the same time and at the same spot in the fish. They are intelligent enough to know who is feeding them and even they can learn to take food from your fingertips.

Additional food should be given 1-2 times per week. Goldfish have different tastes so try to accommodate their preferences with a variety of food.

Quantity of Food for Goldfish

Remember to feed your goldfish what they can eat within a minute only. After 15 minutes remove the excess food as if u left the uneaten food in the tank it will get stuck in the filter, rot and will produce the water.

The important thing to remember is that it is very unlikely that you will ever harm a goldfish by feeding it too little but you could harm very easily by feeding it too much.

Causes of Goldfish Illness

Goldfish may be hardy, but they are not invulnerable. In poor water conditions, goldfish may become victim to parasites, bacterial infections, and fungal diseases. These diseases need to be treated at the right time otherwise it may take over your fish until it exhausted them. Dirty water in the tank lowers the filtration, water and oxygen level which causes the change in the tank’s temperature either too warm or too cold and made it difficult for fish to breathe.

If you are able to diagnose the goldfish diseases early and treat them timely, your goldfish can live for years happily and healthy.

 You have to stay observant as it is very important to diagnose goldfish with the right disease. Medicating your goldfish with the treatment they don’t need can be more stressful as it can make your goldfish actually developing goldfish diseases.
