Crown Helicopter Fish is a kind of special-shaped ornamental fish, which is named after its slender body and helicopter shape. They are mild-tempered and can be mixed with other mild-tempered small and medium-sized fish. They are weak in constitution, sensitive to water quality and environment, and usually like to jump in fish tanks, so it is necessary to add a cover to the aquarium to prevent them from really "flying". When raising this kind of fish, a large aquarium should be provided, and a large area of sand and gravel should be laid on the bottom of the aquarium for them to feed. You can also arrange some aquatic plants and sunken wood at the bottom of the cylinder. If the water quality environment is maintained in daily feeding, it is relatively simple to raise.

1. Water quality: They are sensitive to water quality and environment. In addition to meeting basic water temperature, pH and other conditions, attention should also be paid to the cleanliness of water, which needs sufficient filtration and high dissolved oxygen. The water in the aquarium needs to be changed regularly, about 20% every week.

2. Feeding: Crown three fish like to eat algae and can also receive artificial diet. Frozen beans, potatoes and seaweed can be selected as plant feed. Animal feed can be water fleas, red worms or shrimps.

3. Reproduction: Fish eggs are usually laid on the glass of aquarium, and are taken care of by male fish. Attention must be paid to adjusting water quality during reproduction. Let them lay eggs in water with neutral hardness or weakly alkaline, and the success rate of raising seedlings is higher.
