There is a very good option for all those people who like to enjoy the animal world but do not have enough time that they would like to devote: have an aquarium.
Many people for the short time they are at home cannot afford to have a cat and much less a dog. Fish are animals that barely give headaches and also delight us with a beautiful vision just watching them swim. They do not require the constant attention of their owners, they eat and live quietly in their space. Even so, we must have some basic knowledge to ensure that our new tenants develop correctly in their environment. We must know the main needs that the cold water fish.
How are cold water fish
The cold water fish are perfectly maintained in room temperature waters and withstand (within normality) the oscillations that time produces in its waters. That is the big difference that distinguishes them from tropical water fish, which require strictly regulated water so as not to suffer deficiencies. That is why cold water fish are much easier to maintain and care for.
In general, cold-water fish withstand oscillating temperatures between 16 and 24ºC. There are some specific species such as Locha Dojo fish that will hold up to 3ºC, we will have to inform ourselves in detail of each type. We can affirm that cold water fish are very resistant and that is thanks to the fact that many of them have methods according to their physical characteristics to adapt to extreme situations.
Fish that live in cold waters are very different and diverse thanks to the mutations and breeding controls of breeders. We can find a variety of colors and sizes, as well as fin shapes.
Finally we must keep these tips in mind:
- Note that all fish in the same aquarium eat and swim with each other (they are not isolated), isolation or lack of appetite can warn us of some kind of disease or problem.
- We must always ask the expert for compatibility>
To start conditioning them we will set the temperature of the water at about 18 ° C, with a pH7. In specialized stores we can find a variety of test devices to verify that the water levels and their components are correct.
It is very important to have a filter in the aquarium since water renewal is very necessary (more than in the case of tropical fish). For aquariums that have this type of fish we recommend the backpack filter since, both maintenance and installation are easy to handle and do not interfere with the interior decoration of the aquarium. Having the filter forces us to change 25% of the water every one or two weeks.
It is advisable to put some 3 or 5 cm of gravel like the one you can buy in Miscota at the bottom of the fish tank and preferably choose a artificial decoration Since in addition to not needing any change, the fish could eat the plants and natural algae, some not good for your body.
We can also add ornaments of all types and sizes (as long as the fish has room to swim), we recommend that they be cleaned in boiled water beforehand to avoid intolerances.
Being cold water fish we will not need heaters to keep the water at a specific temperature but still, we can locate a thermometer to learn more about the daily life of our fish.
