Why is my fish swimming fast back and forth?

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.

Why do fish settle at the bottom of the 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 moving so fast?

Fish Swimming Quickly When the water quality in your tank drops below acceptable levels, your fish are likely to become stressed and they may react to that stress by exhibiting abnormal behaviors such as swimming quickly or erratically around the tank.

Why is my fish spinning in circles?

That said, the most common reasons for aquarium fish swimming erratically, depending on what you consider erratic, is either stress (glass surfing), ammonia poisoning and poor water quality (in circles and darting motion), and swim bladder disease (floating to the top, swimming sideways or sinking to the bottom).

How do you tell if a fish is stressed?

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.

Why is my fish spinning around?

How do you calm a stressed fish?

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.

Why is my fish thrashing around?

Causes: Stress in fish is caused by many different factors. High ammonia or nitrate levels, low oxygen levels, improper temperature or a high or low pH can cause stress. If you have a saltwater tank, incorrect salt levels could have a similar effect.

Why is my fish doing flips?

What is this? The impaired buoyancy in fish is caused by a malfunction of their swim bladder. When affected by Swim Bladder Disorder fish will often lose the ability to properly swim. They will float uncontrollably to the top of the aquarium, turned upside down, while still being alive.

Why is my fish swimming around the tank so fast?

There are several reasons why your fish might suddenly begin swimming quickly around the tank, but the two most likely reasons have to do with water quality and breeding.

Why is my fish lethargic at the bottom of the tank?

Keep in mind that lethargic fish do not always spend time at the bottom of the tank – they could be floating near the tank surface or hiding among live plants as well. Another change in behavior you might see in your aquarium fish is rapid gill movement.

Why is my fish dying after a water change?

It is also possible that the process of performing a water change causes stress to your fish and bacteria or other pathogens that are normally present in the tank take advantage of the fish in its weakened state.

Why is my fish hovering near the tank surface?

One of the most common reasons fish begin hovering near the tank surface is that they are seeking oxygen – oxygen levels in the aquarium are typically the highest near the surface of the water so if the oxygen level in your tank water is too low, your fish may begin to seek oxygen from the surface.
