A fish may linger near the surface because he’s trying to breathe more easily. Remember, fish breathe dissolved oxygen—not oxygen that is already combined in the H2O molecule. Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place.
Why do all my fish stay in one corner?
Just like sickness, they stay in the corner because they feel vulnerable. Unfortunately, there’s not much you can do for this one except wait for it to pass. Lastly, they may be doing it because there aren’t enough hiding places in the tank—all fish like lots of hiding places where they can feel safe and rest.
Why is my fish not moving?
As we can see, there are countless reasons that can cause fish to stay at the bottom of the fish tank. The main causes are poor water quality, temperature, inadequate pH and persecution of other fish.
Why is my fish staying near the filter?
The filter creates a current in the water. The fish congregating near the filter intake are taking advantage of that current by positioning themselves where that current flows over their gills without requiring the fish to exert the effort they otherwise would need to in order to achieve this result.
How do you know your fish is dying?
- Some signs you are likely to see when your fishes are stressed or about to die includes loss of appetite, loss of balance, floating upside down, lethargy, and gasping for air.

Why is my fish not swimming around?
One common cause is improper water temperature. If your fish’s water is too hot or too cold, they will be very inactive. Check your heater and verify that your aquarium is at the right level. Other possible causes are overfeeding and improper water quality.
How do you destress a fish?
Trying a stress coat product, which can help remove chlorine, neutralize chloramines and detoxify heavy metals to set up optimal water conditions. It can also help heal skin wounds and torn fins. Reducing overcrowding by moving additional fish to a new tank, or getting a larger aquarium.
Why are fish staying at bottom of tank?
When the water temperature inside your aquarium drops too low, your fish might lay motionless at the bottom of the tank to conserve energy. On the opposite spectrum, if the water temperature rises dangerously high, fish will stay on the bottom because that’s where oxygen levels will be higher.
Why is my fish not moving at the top of the tank?
If fish are experiencing acute stress (i.e., gasping up at the surface, lying on the bottom and not moving, or darting around the aquarium), you can be pretty sure that the water has been poisoned in some way. Maybe cleaning sprays got into the aquarium, or something released toxins into the water.
What’s wrong with my fish?
Weakness or listlessness. Loss of balance or buoyancy control, floating upside down, or ‘sitting’ on the tank floor (most fish are normally only slightly negatively-buoyant and it takes little effort to maintain position in the water column) Erratic/spiral swimming or shimmying.
How do I get more oxygen in my fish tank?
More water movement always increases oxygenation. Add an additional filter or replace the existing filter with a higher capacity unit, if necessary. Other options are using a powerhead, putting a spray bar on the outlet of the filter, or using airstones.
How do I add oxygen to my fish tank?
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. How much oxygen is added depends on how high above the tank you pour the water and how many times you repeat this procedure.
How do I know if my fish has ammonia poisoning?
Symptoms of Ammonia Poisoning in Fish
Initially, the fish might appear to be gasping at the surface for air. Their gills will take on a red or lilac color, making them look like they’re bleeding. Your fish will start losing their appetites, as their bodily functions fail, and they will become increasingly lethargic.
What do stressed fish look like?
Strange Swimming: When fish are stressed, they often develop odd swimming patterns. If your fish is swimming frantically without going anywhere, crashing at the bottom of his tank, rubbing himself on gravel or rocks, or locking his fins at his side, he may be experiencing significant stress.
Does a dead fish float or sink?
Most fish are slightly denser than water, so sink immediately after death. However, like a drowned human, they become more buoyant over time as bacterial decomposition produces gases inside the body. Usually, enough gas builds up in body cavities to make the corpse float, like an inflated balloon.
Can you save a dying fish?
Most dying fish can be easily revived with changes to the water. Maintaining water quality is essential to keeping your fish happy and healthy—and alive. You can buy a fish tank water testing kit at most pet stores. These tests can help you identify any problems with the water, such as high ammonia.
Why are my fish hanging around the heater?
It is likely that the heater is not performing efficiently to warm the entire aquarium evenly. The water temperature should be 24-28 degrees Celsius. One way of rectifying the issue is to ensure good water circulation around the heater.
Why are my fish coming to the surface?
A fish may linger near the surface because he’s trying to breathe more easily. Remember, fish breathe dissolved oxygen—not oxygen that is already combined in the H2O molecule. Naturally, these dissolved oxygen levels tend to be higher near the surface, where interaction between air and water takes place.
What are some signs of ammonia stress in a tank?
Signs of Ammonia stress
- Lethargy.
- Loss of appetite.
- Hovering at the bottom of the tank (especially for surface dwelling fish)

Why do my fish swim up and down the glass?
Fish exhibit many behaviors that tell us how they are feeling, and glass surfing (also known as pacing) is one of them. This is when fish constantly swim up and down the sides of the aquarium glass. One reason they do this is stress. It could mean they aren’t happy in their environment, for one reason or another.
How do you know if a fish is stressed?
What Are Stressed Fish Symptoms?
- Hiding for long periods of time.
- “Flitting” or darting around the tank.
- Frantic swimming; crashing at the bottom of the tank.
- Gasping for air at the surface (a sign of low oxygen levels)
- Scraping against rock or gravel.
