How to raise fairy fish

1. Water quality

Fish culture water first, fairy fish like soft water quality, pH control between 6.5-6.8 on the line, the range difference should not be too large. This will cause discomfort to the fish and cause unnecessary trouble. In addition, the amount of dissolved oxygen in water must be sufficient, which requires the early process of water control, pay attention to explosive oxygen, after all, fairy fish have a relatively large demand for dissolved oxygen.

2. Change water

Another is to change water. Fairy fish are more delicate and have to change water frequently. It's not too much to change water once a day. It's normal. Don't worry about changing too much water. That's what fairy fish like. Just change 1/4 to 1/5 at a time (this is how I change it). You can learn from it. Colorful fairy fish prefer old water, but this does not conflict with changing water frequently, so it is necessary to keep the water constantly updated.

3. Water temperature

It is best to keep the water temperature at about 28 degrees, which is the preferred temperature for most tropical fish. With regard to the treatment and replacement of water, fish friends pointed out that it is OK to change the oxygen and sun-dried tap water every day.
