The vast world of aquarium keeping offers unparalleled experiences, but also poses significant challenges for those who wish to maintain a harmonious and healthy aquarium. One of the most frequently asked questions, especially among beginners, is whether it is safe to mix different species. de peces in the same aquarium. Although the idea may seem attractive due to the diversity of colours and behaviours, the reality is that it is not always a recommended practice.
Incompatibility between species can lead to significant problems. Each type of fish has specific characteristics such as behaviour, natural habitat or diet, which means that not all of them can coexist without conflict. Imagine moving a fish that belongs to the tropical marine ecosystem to a freshwater environment. That situation would be, at the very least, problematic and could result in stress or even death of the fish. Therefore, indiscriminately mixing species is a strategy that should be avoided.
Key factors to consider before mixing species
1. Water parameters: Each species has particular requirements. pH, temperature y hardness of waterIf these parameters are not adjusted to the needs of all fish, stress and disease increase considerably. For example, tropical fish such as guppies require warmer temperatures and a moderate pH, while coldwater fish such as shubunkins prefer lower temperatures.
2. Behavior and compatibility: In addition to the technical aspects, the behavior of the fish is crucial. Some species are territorial o aggressive and may attack or bully smaller or more peaceful fish. For example, betta fish are known for their aggression towards other males or species with long, colorful fins.
3. Aquarium size: Available space is essential. A overpopulation It generates territorial disputes, hinders oxygenation and causes an increase in the levels of ammonia and nitrites in the water, which endangers the lives of fish.
Examples of successful and dangerous mixtures
Compatibility: There are combinations that tend to work well, such as the coexistence of guppies and neons. Both species are peaceful and share similar needs in terms of water temperature and pH. Also, corydoras fish are great companions due to their calm nature and their role as aquarium bottom cleaners.
Avoid: A common mistake is mixing large fish with small species. Large fish such as Oscars may view smaller fish as prey. You should also avoid mixing bettas with fish that have showy fins, as the latter may be mistaken for competitors and attacked.
How to prepare an aquarium for mixing species
1. Previous investigation: Before purchasing any fish, investigates about their characteristics, compatibility and ideal living conditions.
2. Provide shelters: Decorating the aquarium with plants, rocks and logs creates natural hiding places which help reduce stress, as more timid fish can protect themselves in times of conflict.
3. Control water quality: Perform periodic tests to ensure that the water parameters are the appropriate ones.
When it is essential to separate species
There are situations where separating fish is best, even if they initially seemed compatible. Signs that something is wrong include aggressive behavior, fish constantly hiding, or lack of appetite. Having a hospital or isolation tank is a practical solution for these cases.
In addition, during the reproduction of some species, such as guppies or betta fish, it is necessary to separate males and females to avoid aggression or ensure successful mating. If you want to know more about this process, you can read our article on the mating de peces in aquariums.
Although it may seem complicated and requires dedication, keeping an aquarium with different species is an enriching and satisfying experience. The key is to be properly informed, respect the needs of each fish and pay attention to its behavior. Enjoy an aquarium full of life and vibrant colors, but always prioritizing the well-being of its aquatic inhabitants!
