For example, a heater which serves to provide an increase in water temperature in the aquarium. When the water temperature is too cold for fish, you can use this tool to raise the water temperature. Generally, normal temperatures are around 27-32 ° C.

Aquarium Temperature and pH

The optimal temperature for ornamental fish kept in the aquarium is 27-32 ° C. If the water temperature is too high it can reduce oxygen levels in the aquarium.

The ideal water pH for the maintenance of ornamental fish is around 6.5. If the water pH is more or below neutral pH it can stress fish.

For the size of the male and female ornamental discus can grow to about 16.5 cm for two years. So, if you want to keep it for a long time, use an aquarium with large size.

Avoid Ammonia

So that the water change must be done immediately. The high level of dissolved ammonia in the water is influenced by food residue and feces from the fish itself. Therefore, determine the amount when providing feed and change the water regularly.

Routinely Changing Aquarium Water

These ornamental fish need aquarium water that is changed at least 50% every week to reduce nitrates and replenish minerals. Better yet, replace it completely, to remove dissolved ammonia.

The metabolic waste products of ornamental fish are a big contributor to dissolved nitrate in the aquarium. Make sure to do regular water changes.

Aquarium Decoration

Driftwood is great for helping these ornamental pet fish feel like they are in their environment. This will add to the beauty of the aquarium and will also reduce the hardness of the water. And lower the pH for the aquatic environment in the aquarium.

In addition, provide plants to provide oxygen and reduce dissolved carbon dioxide in the water.

Aquarium Lights

Generally, the feed consumed by this type of ornamental fish. Is in the form of insect larvae, worms, and also fruits. Like keeping fish in an aquarium, feeding should not be too much.

Feeding too much will pollute the water in the aquarium. As a result, many dissolved minerals are not really needed by fish.

In addition, it will increase the growth of bad microbes and reduce dissolved oxygen levels in the water. Therefore, give small feeds with frequent frequency.

Give Natural Food

Natural food is food that is taken directly from nature or is readily available in the wild. So there is no need to process it first.

These natural foods include Infusoria and rotifers, water fleas, tubifex worms, blood worms or blood worms, mosquito larvae, shrimp eggs. And brine shrimp. Natural feeding will provide more complete nutrition to fish. In addition, natural food has balanced nutrition.

The Most Suitable Feed

Beef heart is the most suitable feed for this type of ornamental fish. Unfortunately, the heart of a cow can easily contaminate the tank. So, make sure to carry out regular maintenance of the water in the aquarium.

To get the best color from this type of ornamental fish. It is necessary to provide a varied feed both processed and frozen feed. This type of ornamental fish generally does not like feed that floats on the surface of the water. Therefore, try to provide a feed that floats or can sink.

Artificial Feed/Pellets

An artificial feed is fish food made by humans, commonly called pellets. This artificial feed is very practical and easy to find at any feed store. But unfortunately, this artificial feed is not good for this type of ornamental fish.

This can inhibit and slow down its growth if consumed every day. Therefore, use this feed sparingly and also combine it with natural feed.

Bathroom flies are generally a nuisance for these ornamental fish. Bathroom flies often carry parasites that can cause ornamental discus fish to develop various diseases. So that it can cause death.

Therefore, complete the basic requirements, namely by providing an aquarium with a large size and stable clean water. This type of ornamental fish can be kept with other types of fish.
