Background

Clown fish (Amphiprioninae) belongs to the family Hirudinidae of Perciformes, and is a tropical coral reef fish, which is generally named like the horns in the Beijing opera, due to white stripes on the body side. There are 28 natural species known, one from acanthopagrus (Premnas) and the others from amphisarus (ampphirion). Clown fish has a close and inseparable symbiotic relationship with sea anemone in nature, and is also called sea anemone fish.

Common clown fishes include prince clown fish (ampiphion ocephalis), red clown fish (ampiphion frenatus), black double-belt clown fish (ampiphion sebae), red-penetrating clown fish (Premnas biacculus), black leopard clown fish (ampiphion latezonatus) and the like, are mostly distributed in reef sea areas of Indian ocean and Western Pacific ocean, have strange shapes and variable body colors, take sea anemones as habitats with defense functions in nature, attract other fishes to approach, increase the predation opportunity of the sea anemones, are also called as 'sea anemones', are in a typical symbiotic relationship with the sea anemones, and have omnivory.

With the improvement of living standard, the proportion of seawater aquatic animals in the aquatic animals market as a market segment is higher and higher, and clown fishes are favored by more and more aquatic fans as a star variety.

The wild clown fish can be artificially cultured after certain domestication, the gonads of the domesticated clown fish can be artificially bred after the domestication is half a year to more than one year, and clown fish of different varieties can be bred in a hybridization way. At present, the varieties of Picasso, gold bricks, black ice, pandas, DaVinci and the like appearing in the market are all artificial varieties after domestication and improvement. The clown fish group bred artificially has stronger adaptability to the artificial breeding environment and higher survival rate, is in short supply in the aquarium market, and plays a certain role in replacing and protecting wild resources.

Moreover, with the decline of wild natural resources and the protection of marine organism resources in the world, the cost for catching wild clown fish resources is higher and higher, and the artificial breeding and breeding of clown fish is a trend.

A clown fish, fish and vegetable symbiotic circulating water breeding system as claimed in claim 4, wherein a hollowed plastic basket is erected on a precipitation bin (3.1) at the left side of the bottom filter tank (3), a plurality of layers of filter cotton are laid in the frame for primary filtration, a protein separator is arranged in an egg separation bin (3.2) for secondary filtration, a ceramic ring is arranged in a filter material bin (3.3) for culturing nitrifying bacteria groups for tertiary filtration, and a water pump is arranged in a pump bin (3.4).

7. A clown fish, fish and vegetable symbiotic circulating water breeding system as claimed in claim 1, wherein the forced-ventilated drain (6) is arranged in the center of the bottom of the breeding grid (2.2) by drilling holes, and the forced-ventilated drains (6) of all the breeding tanks (2) are connected together through PVC pipes and directly communicated to a sewage discharge pipe (9) to form a forced-ventilated pipeline;

the breeding cylinder (2) is connected with the water discharge pipe (7) and communicated to the left settling bin (3.1) of the bottom filtering cylinder (3) to form a water return pipeline.

8. A clown fish, fish and vegetable symbiotic circulating water breeding system as claimed in claim 6, wherein the top algae tank (4) is communicated with the breeding tank (2) through a drain pipe (7) and is distributed to each breeding grid (2.2) through a pipeline; each breeding grid (2.2) is provided with a valve (8) for adjusting water flow and water pressure;

the water supply pipe (5) connected with the water pump of the pump bin (3.4) and the water discharge pipe (7) connected with the algae cylinder (4) are distributed at the positions of water inlets of the breeding grids (2.2) relatively, a duckbill is connected with the tail end of the water inlets, the position of the duckbill is opposite to the cylinder wall of the breeding grid (2.2), the height of the duckbill is slightly higher than the water level in the breeding grid (2.2), and each valve (8) is adjusted to enable circulating water flow to be formed in each breeding grid (2.2).

9. The clown fish, fish and vegetable symbiotic circulating water breeding system as claimed in claim 1, wherein a layer of ceramic rings with hollow through holes is uniformly laid on the bottom layer in the algae jar (4) for marine ornamental algae to climb.

10. The clown fish, fish and vegetable symbiotic circulating water breeding system as claimed in claim 1, wherein the glass partition plates (10) between the breeding cells (2.2) of the breeding tank (2) are adhered by black plastic paper to prevent clown fish in different breeding cells (2.2) from seeing each other and fighting; a ceramic flowerpot with a proper size and disinfected is horizontally placed at the inner side of each breeding grid (2.2) to be used as a breeding pot.
