Is water movement good for fish?
Proper water movement plays an important role in aquarium fish health management. Many unseen processes vital to fish health occur as water actively moves throughout the aquarium. Water movement is best described as the circulatory system for your aquarium that helps maintain water quality and influences fish health.
However, excessively strong current can cause over-swaying or uprooting of plants, which hinders their healthy growth. For this reason, it is necessary to moderate the water flow in an aquarium.
We generally recommend that on average, you turn over your aquarium volume four times per hour. This means that if you have a 30-gallon tank, you need a pump and filter with flow rates of around 120 gph.
Where Do Fish Sleep? Some fish sleep while swimming, some float motionless, and others hide out of sight from predators.
Moving into a new aquarium tank can be stressful for a fish.
When a sudden, large water change occurs, it causes such a drastic shift in the water parameters that the fish often cannot tolerate it and they die. 2 Those that do not die immediately are stressed and may succumb to disease over the next few weeks.
To prevent this from happening, allow the fish bag to float in the aquarium for 10–15 minutes to acclimate them to the water temperature. (If the fish are in a breather bag that allows gas exchange, place the bag on the aquarium lid for about 30–60 minutes.)
An air pump that is too powerful can wreak havoc in your aquarium. When attached to a sponge filter, it can cause a current strong enough to stress fish that prefer calm water. Or, maybe it's causing your airstone to work overtime, producing so many bubbles that you can't see your fish.
It's quite possible you can successfully move a small- to medium-size tank with gravel, and even some water in it.
For a smaller tank, change out 10%-15% of the water each week. For a larger tank, change 20% of the water each week. If you use tap water, allow it to sit for three days. Use a dechlorinator before pouring fresh tap water into your tank.
Do you need to let water sit in aquarium tank before adding fishes?
Wait for your tank to cycle over a couple of weeks before adding fish. But, if you do want to add your fish immediately, you must follow a specific process. Always ensure you keep your tank water at a consistent temperature; a two-degree fluctuation can cause stress to the fish.
Pouring water from a height, manually stirring the water, or performing large water changes, are some ways to quickly increase oxygen in fish tanks. These methods allow more oxygen to dissolve in the water, and release carbon dioxide.
If your fish are gasping at the surface of the water, take emergency action to immediately increase the tank's oxygen: Perform a large water change (as much as 50 percent of the tank's volume). Then increase the water movement by adding a powerhead, airstones, or even an additional filter.
According to experts, keeping fish in bowls is inhuman for several reasons. Low surface to air ratio, no filters to clean the water and cramped space for the fish are some. Many cities across the world have banned fishbowls altogether. This includes Rome and Monza in Italy, most cities in Sweden and Mexico.
Most fish breathe when water moves across their gills. But if the gills are damaged or water cannot move across them, the fish can suffocate. They don't technically drown, because they don't inhale the water, but they do die from a lack of oxygen.
Most fish need to keep moving even when they're sleeping, so that they keep a constant flow of water moving past their gills to maintain a proper oxygen level in their bodies. For some larger fish, like sharks, this can take the form of swimming at a slower rate when sleeping.
Nerves, brain structure, brain chemistry and behaviour – all evidence indicates that, to varying degrees, fish can feel pain, fear and psychological stress.
Ways to Reduce Fish Stress
Change water frequently to keep nitrate and ammonia levels low. Try adding water conditioners like API Stress Coat Aquarium Water Conditioner, which is formulated to reduce fish stress by 40% by removing dangerous toxins.
Long-term Stress
Throughout the period of adaptation, the fish still prioritizes reacting to the new environment and remains stressed, so its immune system suffers and it is prone to disease. Adaptation normally lasts from four to six weeks.
Whenever more than one fish becomes ill or if you believe your water quality is poor, always perform a series of small water changes. Change 5-10% of the water once a day for 3-6 days. You should avoid large water changes because fish become accustomed to accumulated toxins in the water.
Can I do 50% water change fish?
When adding water back in to the aquarium, use Tetra AquaSafe® to remove the chlorine and chloramine. Try not to change more than 50% of the water, because this will remove the beneficial bacteria and can cloud the tank.
- Swim actively throughout the entire tank, not just hanging out or laying at the bottom, floating near the top or hiding behind plants and ornaments.
- Eat regularly and swim to the surface quickly at feeding time.
You should feed your fish two to three times daily. A few flakes per fish is sufficient. The fish should eat all the food in two minutes or less. Overfeeding can cloud your water and harm your fish.
Osmotic shock happens when the fish is unable to regulate its uptake of ionic compounds, which leads to too much absorption or too much release of fluid. Impaired osmoregulation then causes a condition known as dropsy, which leads to fish swimming erratically after water change.
Very small air bubbles, like those from a fine pore stone, that travel slowly from the bottom to the top of the tank are much more efficient in adding oxygen to the water than large air bubbles which boil the water or airstones which sit near the water surface.
Generally speaking, you should leave the air pump on all the time to help your fish get good water circulation and plenty of oxygen to breathe.
Too much oxygen in water can lead to the potentially lethal gas bubble disease, in which gas comes out of solution inside the fish, creating bubbles in its skin and around its eyes. (Excess nitrogen, however, is a far more common cause of this disease.)
The most effective way to transport water is by re-routing it, since large-scale overland systems can result in massive environmental damage (even when it's bottled)--though as you'll see in the technologies below, even ground transport can be made easier, greener, and healthier.
Never a good idea! The weight and movement of the water puts uneven stress on your aquarium's seals, which could cause leaks later. Plus, fish are extremely sensitive and likely won't survive the stress of sloshing around in a partially full tank.
The best way to move your aquarium fish is by transporting them inside five-gallon plastic buckets. The sturdy nature of these containers will help prevent leaks and spills. In addition, five-gallon buckets are inexpensive and readily available from mass merchandise stores.
How long can a fish tank go without a water change?
Change 10 to 15 percent of the water each week. If your tank is heavily stocked, bump that up to 20 percent each week. A lightly stocked tank can get by for two weeks, but that should be the maximum length of time between water changes as you do not want to place any stress on your fish.
Vacuum the Gravel Fish feces, shed scales, uneaten food, dead bits of plants, and other debris will settle to the bottom of your tank. Vacuuming the gravel every week will remove much of this debris and refresh the tank, brightening the gravel and keeping the tank healthier.
Using a fine filter pad or even better, a poly filter floss will catch all the tiny free floating particles looming in your tank water. Having robust filtration will also help process more waste and help to keep your fish tank clean and safe for all your inhabitants.
If you cannot use your tap water and your tank is small (less than 10 gallons), we recommend you try bottled spring water. This is readily available in most grocery stores and can provide excellent water for your fish. It is not recommended that you switch up brands frequently unless you check your parameters first.
- Float the bag in your aquarium for 15 to 20 minutes in order for the water in the bag to reach the same temperature as that of the tank.
- Open the bag and add a cup of water from your aquarium. Reseal the bag. ...
- After 30 minutes your fish will finally be ready for the big move.
You can't really over-filter an aquarium, but it's fairly easy to under-filter one. Most aquarium filters are rated according to how many gallons the aquarium holds.
The benefits of having good water movement are: Increased oxygen levels through improved water movement at the surface.
Are aquarium air pumps necessary? Not all tanks require air pumps. Fish can live long, healthy lives in tanks without an air pump, and fish will show signs if they are not getting enough oxygen. Some symptoms of oxygen deprivation in fish can be indicative of other causes.
An aquarium fish can stay up to two days without oxygen (in still water) but they still need some more amount of oxygen to breathe and do their essential daily work.
The primary cause of oxygen depletion in a water body is from excessive algae and phytoplankton growth driven by high levels of phosphorus and nitrogen. During the nighttime hours, these photosynthetic organisms consume oxygen through respiration when engaging in active photosynthesis.
Do I need a bubbler if I have a filter?
Whether you need an aquarium bubbler entirely depends on your setup. Many people use bubblers when creating a DIY equipment such as sponge filters – the bubbler is used to “drive” the filter, causing it to draw in water. If your water is not circulating or low on oxygen, then a bubbler could be just what you need!

Fish-keepers sometimes see their pets 'glass surfing' – swimming repeatedly up and down the glass of the tank. This could be the aquatic equivalent of the pacing of a captive tiger that's bored from a lack of stimulation. But the fish could also be stressed from an overcrowded or unfamiliar tank.
Surprisingly, science has found that fish are capable of recognizing their owner's face, even if the owner is standing by the tank with other people. Fish can develop an association between something they like, being fed, with the person who feeds them.
Fish tank substrate refers to the gravel, rocks, sand, etc that is on the bottom of your tank. Certainly it increases your tank's aesthetic appeal, but do you really need it? The answer = no.
The benefits of having good water movement are: Increased oxygen levels through improved water movement at the surface. Food and nutrients are carried to all the tank inhabitants and corals. Waste is carried away from all the tank inhabitants and corals.
A fish can breathe underwater without moving because they use gills that extract oxygen from the water around them while also filtering out other vital things like carbon dioxide.
Fish aren't known for showing affection. Most fish do not want to be touched by humans at all. But Bon Shaw has a Blood Parrot Cichlid that craves human interaction. That fish really loves being petted!
As drinking too much water can disrupt your body's electrolyte balance and lead to hyponatremia, 3 liters (100 ounces) may be too much for some people.
Regulates body temperature. Moistens tissues in the eyes, nose and mouth. Protects body organs and tissues. Carries nutrients and oxygen to cells.
How do I know if my fish tank has enough oxygen?
- Fish will initially react to lower oxygen levels by moving around less. They will swim less vigorously and even eat less often. ...
- Eventually, fish will begin gasping at the surface of the water.

While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
You can add oxygen to your tank by slowly pouring water into it from some height above. The water will pick up air en route as well as drive oxygen into the tank water.
