It is not surprising to see people who house these fish in small tanks and aquariums. Obviously, this is not the best, as they prefer large spaces.

The water in which they perform their functions must have a temperature located close to 18ºC and with a rather basic pH, between 6,5 and 7,5.

As far as food is concerned, they are not very selective, so feeding them does not present any difficulty. With products that we can buy in any specialized establishment, we will guarantee their correct feeding. Although you can also supplement your diet with small pieces of bread and food scraps, but be careful with the latter, since some experts advise that it is good while others say the opposite.

We should feed them around 2-3 times a day, with small amounts of food. Cold water fish can have an insatiable appetite.

They are very curious animals, so the decorative accessories in the water are ideal for them.

Coldwater Fish Diseases and Dangers

Cold water fish can be affected by various diseases and factors that can cause their death.

If we see that our fish swim frequently in the upper area in search of the surface, it is that there is little dissolved oxygen in the water and this can cause them suffocation.

Sudden changes in temperature they are also highly damaging. To avoid this, you must ensure that the temperature remains stable and do not place the aquarium near a place full of drafts.

Another circumstance to take into account is the chlorine in the water, which can alter the pH and cause, among many other things, that the gills and body surface of the fish are destroyed.

Among the most common diseases we highlight the constipation (caused by a very poor diet), virus and bacteria poisoning, necrosis (manifests itself in the form of a state of nervousness in the animal, anemia, abdominal distention, etc.) and fin rot (It is one of the most frequent skin lesions and manifests itself as a whitish line on the edge of the fins that is spreading).
