Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention relates to an egg-laying block that is housed and used in an aquarium for the purpose of spawning ornamental fish breeding in the aquarium. It is intended to provide a block for spawning that is optimal for use.

[0002]

2. Description of the Related Art Cichlid fishes distributed in the fresh waters of the Americas and Africa are so-called substrate-laying fishes that lay sticky eggs on tree roots, rocks, etc., and most of them are habits of protecting eggs and fry by males and females. There is. Among them, discus (Shymphysodon) has a habit of secreting mucilage (discus milk) on the surface of the body and feeding it to the fry that have started swimming to raise the baby. The reproductive ecology, shape and color of the discus are particularly beautiful and therefore belong to the most popular species of ornamental fish today. The spawning of such fish has a habit of spawning eggs on the outer surface of the wall which is almost vertical.

Here, as the egg-laying tool to be used by being housed in the water tank including the above-mentioned discus, a brick,
Use building materials such as slate, PVC pipe, tiles,
The plant pots or vases were placed in an inverted state for the purpose of spawning. In other words, in the past, it could be said that there is no merchandise that has been theoretically supported and established as an egg-laying tool.

[0004]

[Problems to be Solved by the Invention] When the above-mentioned building materials such as bricks, slates, PVC pipes, and tiles are used, it is possible to prevent fine dust from accumulating on the bottom and raise a cleaning facility when breeding these species of ornamental fish. In order to achieve this, the principle is that gravel is not laid on the bottom of the aquarium, so there is a drawback in that the stability in the housed state is extremely poor if it is such a building material.

Further, when a flower pot or a pot is used, since it is placed in an inverted state, the internal and external flowability of water is hindered,
Therefore, there is a problem in that the water inside is easily decomposed and the water quality in the water tank is deteriorated. Further, in the case of a flowerpot, there is a drawback that it has a hole in the bottom portion, which causes a problem that fry cannot get in and out of the pot.

The present invention solves the above-mentioned problems in the prior art and provides a novel product called an ornamental fish spawning block.

SUMMARY OF THE INVENTION The present invention comprises a top plate portion 1,
For the spawning of ornamental fish, which has a frame-like configuration in which a large space A is formed in the center by a vertical surface forming plate portion 2 and a steeply inclined surface forming plate portion 3 which are vertically provided on both side edges of the top plate portion 1. It provides blocks.

[0007]

1 to 3 show a first embodiment of the present invention. In the figure, 1 is a top plate portion,
A vertical surface forming plate portion 2 is vertically provided on one side edge thereof. Three
Is a steeply inclined surface forming plate portion that is vertically provided on the other side edge of the top plate portion 1, and the plate portion has an inclined surface of about 50 to 80 degrees. Reference numeral 4 denotes a bottom plate portion formed so as to connect both lower end edges of the vertical surface forming plate portion 2 and the steeply inclined surface forming plate portion 3.

That is, in the above-mentioned embodiment, the top plate portion 1,
The vertical surface forming plate 2, the steeply inclined surface forming plate 3, and the bottom plate 4 are formed in a rectangular frame shape so that the outer surface and the inner surface of each plate are used as a spawning surface. ing. The space portion A formed in the center is used as a space for fish to pass through and also as a water circulation space.

FIG. 4 shows a second embodiment of the present invention, which is constructed by omitting the bottom plate portion 4 from the first embodiment described above. That is,
By omitting the bottom plate portion, it is possible to secure a stable mounting state without being influenced by the unevenness of the bottom surface of the water tank when mounting in the water tank.

FIG. 5 shows a third embodiment of the present invention, and the embodiment shown in FIG. 4 has a configuration in which a reinforcing plate portion 5 is attached. That is, it is configured to compensate for the deterioration in strength due to the omission of the bottom plate portion.

FIG. 6 shows a structure in which the reinforcing plate portion 5 in the embodiment shown in FIG. 5 is replaced with a wide shelf-shaped plate portion 6. With such a configuration, the shelf-like plate portion 6 serves as a reinforcing material, and at the same time, spawning on the shelf-top plate portion 6 is allowed.

FIG. 7 shows a configuration in which leg-shaped projections a are provided at both ends of the lower end edges of the vertical surface forming plate portion 2 and the steeply inclined surface forming plate portion 3. As a result, the placement in the water tank becomes point grounding instead of the surface grounding or the line grounding as in each of the above-described embodiments, and therefore is not affected by the irregularities on the water tank bottom plate portion, Stable placement is ensured.

The present invention is intended to be accommodated and mounted in a water tank in an upright state as shown in FIG. 1 for use. In the case of a substrate-laying fish such as a discus that lays sticky eggs, eggs are mainly formed on the outer surfaces of the vertical surface forming plate portion 2 and the steeply inclined surface forming plate portion 3. By the way, it was confirmed by observation that spawning is mainly performed on the vertical surface forming plate portion 2 in the case of young fish and in the steeply inclined surface forming plate portion 3 in the case of ripe fish, but this is not the case for all cases. However, depending on the character of the fish, the vertical surface forming plate portion 2 or the steeply inclined surface forming plate portion 3 may be arbitrarily selected to lay eggs.

In addition, the use of standing up as described above is in the case of fish such as discus and angelfish,
In addition, a substrate spawning fish belonging to the cichlid family can be used by placing and placing it in a laid-down form, laying eggs on its outer side and inner side, and raising fry inside.

In the present invention, the whole is mainly formed by a pottery, but other than this, it may be formed by an appropriate material such as wood, a synthetic resin agent, or a non-corrosive metal material.

Further, in the illustrated embodiment, each of the top plate portion 1, the vertical surface forming plate portion 2 and the steeply inclined surface forming plate portion 3 has a flat plate shape. May be configured to use a plate material having an arcuate outer surface or arcuate inner and outer surfaces, or a decorative plate-like material.

[0017]

According to the present invention, a top plate portion 1, a vertical surface forming plate portion 2 and a steeply inclined surface forming plate portion 3 vertically provided on both side edges of the top plate portion 1 have a large space portion in the center. Since A is formed in a frame shape, the vertical surface forming plate portion 2 and the steeply inclined surface forming plate portion 3 are formed.
Is a very good spawning surface, and a desired spawning surface can be selected based on the juvenileness or characteristics of the fish.

Further, the present invention has a large space A in the central portion.
Since the present invention is configured so as to form a fish, even if the present invention is placed in a tank, it hardly interferes with fish swimming.
At the same time, the presence of the space A, after spawning on the outer surface of the plate portion, the parent fish can swim as if it goes around both the inner and outer surfaces of the plate portion, so the egg can be sufficiently protected for the parent fish. Therefore, the parent fish can be given a sense of security.

Further, the presence of the space portion A does not impede the running water in the aquarium and imparts the variability of swimming with respect to the fish, so that the effect of relaxing the tension of the fish is exhibited.
