Abstract

PROBLEM TO BE SOLVED: To provide a seawater fish bottle aquarium without water change, in which a bottle is prepared by placing natural stones in which seawater-compatible bacteria live in seawater, and one person can breed an aquarium and easily observe seawater fish.
SOLUTION: In a seawater fish bottle tank which does not require water change, a tank for seawater-compatible bacteria and seawater 4 on which seawater-corresponding bacteria have been established, a bottle 1 for accommodating them, and a lid 2 for sealing the bottle 1 are provided.

Description

  The present invention relates to a seawater fish bottle tank using seawater and natural stone (koga stone) which is used particularly for school education and ornamental use.

Conventionally, such materials used for school education have been used mainly for freshwater fish using freshwater (medaka, etc.).
The art of freshwater fish is well known. For example, in the “water-change-free bottle tank” disclosed in Patent Document 1, freshwater fish are mainly raised in a bottle tank that does not require water change.
JP 2000-209797

  However, the configuration of Patent Literature 1 is mainly intended for freshwater fish (medaka, etc.), and has a disadvantage that it is difficult to breed marine fish in a bottle tank for a long period of time.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem and its effects will be described.

The water tank that does not require water change shown in FIG. 1 is provided with a natural stone and seawater in which bacteria for seawater have been fixed, a bottle for storing these, and a lid for sealing the bottle.

the above

In the seawater fish bottle aquarium requiring no water change described, the natural stone is koga stone.

the above

In the described water-requiring saltwater fish bottle aquarium, the coga stones are arranged in a mixture of sand-like (about 2 mm or less) to 10-20 mm in diameter.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a seawater fish bottle tank that does not require water change according to a first embodiment of the present invention.

  In this figure, 1 is a bottle, 2 is a lid, 3 is seawater, 4 is saltwater fish, 5 is seawater-corrosive bacteria-fixed koga stone having a diameter from sandy (about 2 mm or less) to 10 to 20 mm. Are mixed, and three kinds of seawater-compatible bacteria are settled on three kinds of large, medium, and small cogaites.

  According to the present invention, first, a coga stone 5 of various sizes (large, medium, and small) in which seawater-adaptive bacteria are easy to live is placed in the bottle 1, and the seawater 3 is put therein, and seawater fish (such as flounder or flounder) is placed therein. Fry such as sea bream, body length 10 to 15 mm) and so on are fed and bred.

  In a narrow aquarium, harmful ammonia and nitrite are generated from fish from the remaining bait and marine fish droppings. However, the above-mentioned cogaite 5 is a natural zeolite preferred by seawater-corresponding bacteria that decompose two kinds of harmful substances, ammonia and nitrous acid. Therefore, the bacteria are surely settled and proliferated, and generation changes are repeated. Therefore, there is no need to replenish the bacteria on a regular basis.

  As described above, there are cyanobacteria that generate oxygen and two types of nitrifying bacteria in cogaite, and they function to keep the water environment in which marine fish live in an optimal condition.

FIG. 2 is a seawater fish bottle tank that does not require water change according to a second embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

  This embodiment is characterized in that air can be supplied to koga stone on which seawater-adaptive bacteria are fixed. That is, a small air pump 21 is disposed outside, and a tube 22 having an air discharge hole 23 provided at the bottom of the seawater-corresponding bacteria-fixed koga stone 5 is disposed from the outside of the bottle 1 to the inside. Air is sent from the small air pump 21 through the tube 22, and the air is supplied to the seawater-compatible bacteria-fixed koga stone 5. Reference numeral 24 denotes an exhaust hole formed in the upper part of the lid 2.

  As described above, when air is fed into the coga stone, aeration is performed, and the ability of decomposing bacteria corresponding to seawater is further increased.

  The present invention is not limited to the above embodiment, and various modifications are possible based on the spirit of the present invention, for example, a bottle may use a PET bottle used for soft drinks and the like. However, these are not excluded from the scope of the present invention.

The effect of the invention

  As described above, according to the present invention, the following effects can be obtained.

  (A) Prepare a bottle of natural stone in which seawater-adaptive bacteria live in the seawater. Can be provided.

  (B) It is possible to provide a maintenance-free ornamental aquarium at a low price without the need for breeding.

  1 is a seawater fish bottle tank that does not require water change according to a first embodiment of the present invention.   It is a seawater fish bottle tank which does not require water change showing a second embodiment of the present invention.
