A concern among many pet owners is whether their fish are feeling depressed. Do aquarium fish get depressed? Do they feel stress in an aquarium environment, and does this lead to depression? Fish mental health is a topic that has not been studied much, but there are some answers to these questions that I’ll try to deliver to the best of my ability.
Do aquarium fish get depressed?
In general, it can be assumed that all animals may experience some level of stress when placed into a new environment; however, the scientific evidence for such effects on aquatic species is minimal at best. It’s important to note though that because we don’t know how they would react if they were stressed out in nature because of lack of research work done, there could be some unknown factor influencing the way they behave in a certain environment.
There are many reasons fish may show signs of depression, but they can usually be categorized into two groups
Social causes of stress could include changes in water quality or tank mates, while an environment with poor filtration would cause both physical problems as well as mental ones. Environmental stresses that affect the behavior of aquarium fish have been documented for decades, yet there is a lack of knowledge about this potential problem when it comes to their natural habitat. One hypothesis suggests that because we know so little about them in nature (i.e. how much territory they need), what factors are influencing their moods etc., our assumptions might not be correct at all times and therefore any conclusions drawn from studies on captive aquatic animals would prove inaccurate.
what are the symptoms of depression in fish?
I have been receiving a lot of questions regarding how to find out if a fish has mental health issues. Well, there are quite a few symptoms that can indicate your Fish is in depression. A fish with depression might:
- Act lethargic and unengaged in social interactions;
- Spend more time hiding or resting on the bottom of an aquarium. They may not bother to patrol their territories, eat well, or groom themselves as often as a healthy fish would;
- Do less exploring when placed into new environments such (ie new tanks); this is particularly evident in some species like goldfish who have been found naturally bold foragers. In contrast, they become passive when stressed or depressed;
- Have slower responses to stimuli than other fishes that are feeling normal.
What causes depression in fish?
There are many potential explanations why aquatic animals get depressed which include having insufficient living space, being unable to control their environment, not being able to swim as much they would want, or some form of injury. It is imperative to monitor any unusual behavior of your fish to get a better idea of what is causing this behavior. Sometimes, fish are depressed because they don’t have enough to eat or have too much to eat.
A lot of people are unaware that aquarium fish can get stressed. Fish have been known to experience more stress in an aquarium than they would in their natural habitat. There is a number of reasons why this may happen.
- lack of space
- excessively high levels of water pollution such as ammonia, nitrates, and nitrites which are toxic for them; bright lights from the tank lid or filter area, etc. These things cause the fish to go into fight-or-flight mode which puts them under great mental stress (which we know causes depression).
- Stress also occurs when there are not adequate hiding places like plants, caves, or other decorations inside the tank.
How to cure fish depression?
Cure stress in aquarium fish?
- Place more plants or decorations
Do you need more plants or decorations such as rocks and stones in your aquarium to make it feel like home? This will help reduce any stress that they’re feeling from being inside of an enclosed space all day long.
- Leave Enough Room for Fish
Another option is making sure there’s enough room for swimming; which means having at least 50 gallons of water per inch of body length (about 20 gallons). The bigger the better!
- Make sure there are hiding places for Fish
Make sure there’s plenty of hiding places also – imagine how claustrophobic you would feel in a narrow and dark space, same goes for your fish as well.
- Keep A check on Water Quality
Another way to treat depression in fish is to keep an eye on the water quality. Do your best to make sure ammonia and nitrite levels are in check because they can both contribute to emotional distress when you’re doing a regular water change.
- Reduce Light
Consider reducing the amount of light in their surroundings.
- Avoid Overfeeding The Fish
Overfeeding and starving both can cause stress in fish, so make sure to study the feeding schedule required for your fish as it may differ from what you have perceived.
- Make Sure sufficient water is available
Ensure that there is always sufficient water in the tank.
- Provide some activity to your fish
Another tip would be to provide some form of stimulus for your pet, whether it be through an environmental change or providing it with a friend.
- Don’t intervene without proper monitoring
Do remember that you should never intervene without monitoring the behavior closely as this could lead to further stress. As soon as it starts behaving normally again, remove any changes made during these interventions.
