Beginner aquarists are often interested in the question: “Why does a goldfish constantly lie at the bottom and breathe heavily?” Such behavior can be caused by a variety of factors, and you should not panic. If the fish lie at the bottom of the aquarium, swim slowly at the bottom of the tank, this does not always mean that they are sick and are going to die.
What aquarium fish swim in the bottom layers of the aquarium
Immediately, we note that for some species of fish it is common to lie down or swim slowly near the very bottom of the aquarium. Thus, speckled catfish and other varieties of the corridor swim in the bottom layer of reservoirs. These individuals are sanitation aquarium. They eat organic particles from the bottom, scraping algae that have accumulated on its surface.
In the lower layers of the aquarium also live neons. bright schooling beautiful fish with iridescent scales. Swimming closer to the bottom, this species of fish feels comfortable and safe.
At the bottom of reservoirs, aquariums often spend time cichlid fish, loachfish. They love to loosen the bottom in search of food, dig up aquatic vegetation. In addition, floundering in the gravel, the sand of the fish thus clean their scales from mucus.
Many species of fish sink to the bottom of the aquarium or drift slowly in the lower layers of the water at night. This is quite normal. During the day, fish are more active than at night.
If goldfish sink to the bottom of the reservoir, this behavior is typical of new individuals that have recently been settled in the aquarium. For several days the fish will adapt to new environmental conditions, content. As a rule, adaptation takes place in the secluded corners of aquariums. In the first weeks at the bottom cichlids, goldfish, labyrinth, tooth-tooth prefer to dwell.
After acquiring a goldfish, many aquarists are faced with the fact that it always lies at the bottom of the aquarium and practically does not swim. As already noted, this behavior may be associated with the adaptation of a new pet, which takes from several days to several weeks. Do not forget that the goldfish experienced stress and even, perhaps, shock.
Watch the behavior of the goldfish carefully. If she does not swim up for food, lies on her side. do not panic. After passing through the natural stage of acclimatization, the behavior of the goldfish is normalized and the pet will delight you with its grace and beauty.
Among other reasons that can provoke similar behavior in fish, can be identified:
- improper conditions of detention (temperature, lighting);
- unsuitable size of the aquarium;
- poor water parameters;
- "Young" aquarium;
- viral, bacterial, parasitic diseases;
- pathology, gastrointestinal diseases
- overfeeding, obesity;
If a goldfish is breathing heavily, has become sluggish, inactive, is slowly swimming or is turned on its side, such a condition of the nurse can be caused by adverse conditions of detention. Incorrect temperature, too warm or, conversely, cold water leads to disruption of metabolic processes, can cause systemic disruptions in the body of fish. With a strong overheating of water decreases the amount of oxygen, which also detrimental effect on the state of aquarium fish.
Violation of the temperature regime is possible after a water change or due to breakage of the heater. Therefore, to create the most comfortable conditions for the inhabitants of the aquarium, systematically follow the indicators of the water thermometer.
Tip! If the goldfish constantly lies at the bottom, most likely, the water parameters are not suitable for it, therefore we recommend using special tests to check the water for the content of ammonium compounds. It is also worth to inspect the filters, filter systems for contamination.
Another reason for goldfish to keep close to the bottom is pebbles, gravel in the stomach. This type of fish loves to rummage in stones, sand in search of benthos, worms, therefore often with clump of food slow-moving fish swallow pebbles. This leads to poor coordination of movements. Fishes get hard to swim and keep balance. It all depends on the size of the stone that fell into the pet’s stomach.
If goldfish lie on the bottom, one of the possible reasons for this behavior may be an insufficient volume of the aquarium. When planning to contain goldfish, it is necessary to take into account that 50 liters of water are required per individual. If you keep fish in cramped conditions, this leads to rapid pollution of the aquatic environment, increasing the concentration of nitrates, nitrites, and as you know, these compounds do not tolerate most species of aquarium inhabitants, including goldfish.
If a golden fish lies at the bottom, breathes heavily, it becomes sluggish, a rather common cause of this condition is a young aquarium, in which the necessary eco-balance of the aquatic system is temporarily absent. To avoid one of the most common mistakes of beginning aquarists, you need to not only prepare water, purchase and launch equipment, but wait a while until a colony of bacteria grows in the biofilter, which will process nitrates, nitrites, and only then start aquarium fish.
Injuries, diseases of aquarium fish
If you are wondering why a goldfish swims slowly, constantly lies on the bottom, swims on its side, turns over on its back, breathes heavily, but the conditions of detention are not violated. this behavior can be triggered by injuries or diseases of various etiologies.
It is known that Betta Fish have a cocky temper and often arrange real aquarium battles, during which they hurt each other. If the swim bladder is damaged, the coordination of movement is disturbed in the fish, it becomes inactive, kept separate from other inhabitants of the aquarium or lies at the bottom.
If a golden fish, which up to a certain point felt well, was actively swimming in the aquarium, ate normally, but you found it at the bottom somewhere on the side or in the corner of the tank, this indicates that the pet is sick. Depending on the accompanying symptoms, we can conclude which disease is being referred to and how to deal with it.
Do not forget that aquarium fish are subject to various specific diseases. Overfeeding, pathologies of the liver, gastrointestinal tract, edema Malawi, hexamitosis, inflammation of the gallbladder lead to the fact that the fish weakens, sinks to the bottom, swims on its side. Many diseases are characterized by severe, difficult breathing, lethargy, apathy, passive behavior, refusal of food.
If the fish lies at the bottom and breathes heavily, it swims slowly with its gills wide open, its fins are glued together, and the scales are covered with a bluish bloom, in which case it may be suspected that the fish have chylodennelosis. The disease causes a parasitic ciliates, and in order to prevent the death of fish, it is necessary to start treatment immediately.
What to do if goldfish swim or lie at the bottom of the aquarium
If the fish is injured, it should be deposited as soon as possible in a separate tank or tank with pre-prepared water. It is also possible to fence off part of the aquarium with glass, thereby creating an additional section.
If the fish keep the bottom layers, pay attention to the quality and quantity of feed you give them. Overfeeding can provoke liver obesity, diseases of the digestive tract organs, and cause passive behavior. Remember: obesity is deadly for all aquarium fish, so cut down the feed, arrange a fasting day for goldfish.
Pay attention to the condition of the water, conduct its research using special tests.
In order for the adaptation period to pass as quickly and painlessly as possible for goldfish, during transportation in cold or too hot periods of the year, it is necessary to monitor the temperature of the water in the transport tank. At home, measure the parameters of the water in which the fish arrived, and compare them with the parameters in the aquarium. If the temperature differs by more than one degree Celsius, place the bag of fish for a while in the aquarium, so that the temperature smooths out.
In the event that the pH differs by one or more, we recommend moving the goldfish with water from the transport tank to a separate container. In addition, it is necessary to carry out aeration from the compressor there and gradually add water from the aquarium within an hour, until the pH values become equal.
Tip! Experienced aquarists recommend adding Tetra AquaSafe to the water of a shipping container, which will not only remove chlorine and heavy metals from water, but also enrich it with useful vitamins and minerals. The adaptation period will be faster, and the fish will not be exposed to severe stress.
If you suspect that the pet is sick, deposit it in a separate container. Add Tetra Medica ContraIck, Tetra Medica General Tonic, other medications to the water, after consulting a veterinarian or experienced aquarists.
To avoid pebbles in the stomach of goldfish, two types of soil can be used in the aquarium. fine gravel with a particle size of 2–3 mm or large pebbles with a diameter of more than 1 cm. If the fish accidentally swallows small pebbles, it will not harm its health, but large the size of the stones goldfish simply can not swallow.
