Common fish are lantern fish, fighting fish, colorful angelfish, red flag fish, peacock fish, traffic light fish, clown fish, blood parrot and so on.

3. koi fish

Koi fish is a huge and noble ornamental fish with many colors such as red, white, yellow, gold and purple. The main varieties are dazheng tricolor, red and white tricolor, gold, showa tricolor and good luck. Koi fish is an omnivorous fish.

4. Marine fish

There are many kinds of marine fish, such as angelfish, clown fish and cannonball fish. The water for raising this kind of fish needs to reach a certain salinity. Seawater essence can be used to prepare seawater with the mass fraction of 1.020~ 1.050, and the temperature is 17~27℃, so it needs aeration to increase dissolved oxygen.

(1) angelfish. Angel fish like to rest on rocks, corals or rotten wood. Fish of the same species should not be mixed together, otherwise they will attack each other.

(2) Clownfish. Clownfish can have anemones, and two or more red or white clownfish should be kept together.

Two, domestic ornamental fish water supply and water change

Tap water is generally used for family fish farming, but the bleaching powder in tap water will produce free chlorine, which needs to be removed before it can be used. There are two ways to remove chlorine.

1, aeration method

That is, put the water into the bucket and dry it in the sun for 3-5 days; If it is indoors, it should be left for about a week (depending on the water temperature and chlorine content).

2. Chemical chlorine removal method

Add sodium thiosulfate into tap water, and the concentration is110000. Sodium thiosulfate is a colorless and transparent crystal, which is called "hypo" in the ornamental fish market. Put 2~3 capsules into a bucket of water and stir well. If you feed tropical fish with tap water, you should also pay attention to the water temperature, raise it to a suitable range, and adjust the hardness and acidity of the water. Pure water can be added to reduce the hardness, and baking soda or sodium dihydrogen phosphate can be added to reduce or increase the acidity of water.
