How to raise rainbow sharks for beginners:

1. Water quality: Rainbow sharks have very wide temperature requirements. Generally, they can survive when the water temperature is controlled within 20~29 degrees. Rainbow sharks have pH requirements for water. The pH value is about 6.8~7.5. It is necessary to maintain the circulation of the water flow and remove toxins in the water regularly, so as to provide a good growth environment for rainbow sharks.

2. Container: Rainbow sharks are not small and have strong territorial awareness, so it is best to Use large tanks more than 1 meter long for breeding. Coral sand can be spread on the bottom of the tank to filter the water and maintain the clarity of the water.

3. Food: Rainbow sharks can generally starve for about 20 days, but it is best not to starve rainbow sharks for a long time, otherwise rainbow sharks will get sick or deformed. After the rainbow shark eats, an oil film will be formed on the water surface, which can be removed by dragging it on the water surface with absorbent paper.
