Do Fish Get Sad When Other Fish Die? 

Humans and sentient animals both experience a feeling known as “sadness.” There has long been a misconception that fish are emotionless and insensitive. However, when a tankmate perishes, fish might exhibit indications of mourning and despair.

Similarly, a study performed by Florida International University examined the effects of antidepressants on fish in the Florida Keys. The results show that FLX causes a low-cortisol phenotype in both male and female fish. This condition reduces exploratory behaviors for two generations and alters critical coping behaviors. And often, people ask me, “Do fish get sad when other fish die?” The short answer to this is, no, not usually. However, there are some signs to look for if you want to know if your fish is feeling sad.

Symptoms of depression in fish

Symptoms of depression in fish include a lack of interest in food and the surroundings. These are the same behaviors that occur in humans when they are depressed. Fish can also experience depression because of stress.

The most common symptom of depression in fish is their decreased time swimming. They also tend to linger in one spot near the bottom of the tank. This is usually a sign of poor water quality. The presence of ich, a fish disease, and a lack of oxygen in the water are other reasons for this.

Interestingly, researchers have discovered that the human brain and the fish brain have a lot of similarities. This includes the brain’s serotonergic system, which is associated with depression, hunger, and sleep. Several studies have also discovered that depressed patients are depleted of omega-3 fatty acids found in fish.

There is a strong link between the infrequent dietary consumption of fish and depressive illness. Women who ate fish less than once a week were found to have a higher incidence of mild to severe depressive symptoms. However, it is unclear if this results from the fish’s high omega-3 fatty acids or if the fish itself is depressed. Regardless, the results were consistent with cross-national comparisons of fish consumption and the prevalence of depressive disorders.

The zebrafish is a popular model for research into the behavior of depressed fish. When placed in a newly introduced tank, the zebrafish showed a curious, lethargic behavior that resembled depression. Eventually, the zebrafish showed the classic signs of depression: a lack of interest in food and the environment.

Other fish that show signs of depression include bettas. These fish are often the victim of poor care and can suffer from the following symptoms: acting differently, exhibiting several behaviors, and even dying.

The fish brain has an elaborate and complex system, and it’s often used in studies of psychiatric drugs. Behavioral biologist Culum Brown from Macquarie University in Sydney has done many studies on the fish above. His lab has published more than 100 papers on fish cognition. His work is based on the fact that fish have a similar neurological system to humans.

The fish brain has very similar neurochemistry to humans, so it’s no surprise that they can show similar behavior to the human brain. However, the human brain can perform other sophisticated behaviors like swimming. If your fish suffers from depression, it might be time to upgrade its living quarters. The environment may need to be enriched, and the fish may need more water or a different feeding schedule.

Other signs of stress in aquarium fish include changes in water currents, lighting, and the absence of hiding places. In extreme cases, the fish may need to be relocated from their tank.

Tests for antidepressants on fish

Several studies have been conducted to evaluate the effects of antidepressants on fish. They have revealed the transgenerational effects of these drugs, which may have implications for the future of the fish population. The drugs enter the aquatic environment through effluent water and wastewater sources, such as hospitals and households. As a result, the drugs can affect growth, reproduction, and immune function. The drugs may even enter the fish’s brain, affecting behavior.

The studies were conducted to evaluate the effects of two commonly prescribed antidepressants on fish. Fluoxetine hydrochloride (FLX) is a selective serotonin reuptake inhibitor (SSRI) that causes changes in feeding and survival processes in aquatic organisms. FLX is typically used as the first line of treatment for pregnant women suffering from affective disorders. In the present study, fluoxetine was evaluated on both zebrafish and African-clawed frogs. The highest tested concentrations of antidepressants resulted in 100% mortality of zebrafish embryos and African clawed frog embryos.

Edition, gene expression analysis revealed that the pathways that control cortisol synthesis are altered in the third generation.

The research was conducted in collaboration with Florida International University and Umea University. The researchers studied fish in Biscayne Bay and the Florida Keys. They found that the fish were less fearful when exposed to anti-anxiety medications. However, the researchers also found that venlafaxine (marketed as Effexor) reduced the speed of minnows’ response to stimuli indicating possible predators.

Several pharmaceuticals were detected in the wastewater. Antidepressants were among them, as were heart medications, opioids, antibiotics, and pain relievers. Some pharmaceuticals, such as amitriptyline, decreased body length in zebrafish and common carp. Similarly, high amitriptyline concentrations decreased heart rates in zebrafish. The effects of the drugs on juvenile chinook salmon were also observed. In these studies, the effects of the drugs on the fish were observed at concentrations 300 times higher than the therapeutic level.

Another study, conducted by St. Cloud State University, exposed minnows to venlafaxine and found that the minnows swam slower and showed decreased reaction time to stimuli indicating possible predators. However, the minnows’ response time did not slow down when exposed to nanogram concentrations of fluoxetine.

The tests were conducted to evaluate the effects of two commonly prescribed antidepressants, fluoxetine, and citalopram, on fish. Several drugs were tested, including amitriptyline, nortriptyline, clomipramine, citalopram, sertraline, fluoxetine, and sertraline hydrochloride. The drugs were evaluated as single compounds, combinations, or mixtures. The drugs were evaluated as environmentally relevant concentrations in order to assess whether or not they have a toxic effect.

Getting over the loss of a pet

Getting over the loss of a pet fish is an emotional and stressful experience. It is essential to take good care of yourself. This will help you cope with the loss and move forward in your life.

Do fish have any sense of when other fish are dying?

Most animals in the animal kingdom lack self-awareness and a sense of identity, except for dolphins. They, therefore, probably do not have an abstract awareness of their impending doom.


What happens when one of the fish dies?

Removing dead fish is best since their bodies will soon decay in the warm, bacterial-filled water. Water pollution from a corpse puts the health of other fish in the tank in danger. The last thing you want is other fish eating its body parts. If it died of sickness; therefore remove it right away.

Can fish feel sad?

Fish exhibit depressive symptoms and have neurochemistry that is comparable to that of humans. Some fish species have been shown to exhibit signs of severe depressive illness, according to recent investigations.

Can fish experience pain?

Fish do experience pain. Although it probably differs from what humans experience, it is nonetheless a form of pain. This is because fish contain nociceptors, which are neurons with the ability to sense dangers, including high temperatures, extreme pressure, and caustic chemicals.
