If you want to have a moving and unusual pet in your home glass pond, pay attention to this kind of fish, like aquarium sharks. Do not be alarmed by the name - they are not relatives of marine predators, although there is undoubtedly an external resemblance, and sometimes in character too. And in order to make a choice, consider their features.
Conditions of detention
In order not to condemn their pets to a joyless existence in a confined space, and even in uncomfortable conditions, you should pay attention to the features of the content.
Decorative fish shark has a somewhat specific disposition and requires increased attention to itself. Here are just the general rules:
- Constant water temperature - from 24 to 29 ° С.
- The volume of the aquarium is at least 40 liters.
- Daily change of about 30% of the water in the tank.
- Good filtration and aeration of the aquarium.
As for the interior arrangement of the glass house, here you can afford almost everything. But note that under a layer of sand or small pebbles, you should certainly lay a layer of large pebbles. Plants should be planted either in the soil itself, but deeper, or placed in special clay pots, carefully having strengthened them. The fact is that aquarium sharks are very mobile fish.
For the convenience and comfort of such unusual pets, arrange several grottoes and stone caves at the bottom.
The most popular types of aquarium sharks
Despite their awesome name, these fish are quite peaceful and do not annoy their neighbors in the underwater dwelling. They are only seemingly so fierce and scary, but get along with almost everyone.
Often there are names: pennant pangasius, freshwater or pennant shark. It is this fish that has the greatest outward resemblance to its predatory tees. In the wild, specimens up to 1.5 m long are found. In captivity grows no more than 60 cm. Consider this when choosing a container.

The fish has a rather timid character and, with the slightest danger or anxiety, can jump out of the aquarium or torpedo the walls of its glass house, which is harmful, especially to itself.
Feed should be slices of frozen fish, squid or dry granular food. But he doesn’t feel the measure in food and can even get sick due to overeating. Therefore, it is recommended to feed twice a day, observing the time schedule. Also twice a week it is recommended to arrange "fasting" days.
Warning! Do not place small fish with this freshwater shark. Because of her gluttony, she can simply gobble up her neighbors, mistaking them for food.

Black two-tone shark
Perhaps the most spectacular and beautiful inhabitant of a home aquarium. She has a velvet-black body and a bright red tail. For the opportunity to watch such an unusual, graceful beauty, many aquarists forgive her hard and aggressive character. Photo is proof of that.
A predatory little fish that has the most unusual gift - it glows. This is due to the presence of special plaques of photophores on the abdomen and fins. In the case of excitement or excitement, the glow increases, at rest - almost imperceptibly.
This is an ovoviviparous fish, capable of reproducing up to 10 sharks in one spawning. Mom shark eats plankton, which breaks with sharp teeth. Therefore, feeding such fish from your hands is fraught. Dwarf sharks live and breed in almost ideal conditions. If you are ready for such sacrifices - then go for it.
How to choose?
If you have definitely decided for yourself that you want to breed aquarium sharks as decorative fish, you should know the aspects of choosing both the individual and the house for her.
We choose houses according to this principle:
- For the bottom shark, an aquarium of square or rectangular shape with sharp corners is suitable, since it can breathe, lying calmly at the bottom.
- For a pelagic shark, the best option would be an annular aquarium, or at worst with rounded corners. This fish rushes through the glass house with high speed and it is difficult to "brake" before the obstacle, which affects the quality of life and can lead to disease.
- The volume of the vessel for one individual is at least 35-40 liters, taking into account the fact that with intensive growth, a larger house will be required.
You should not put several species of sharks in one aquarium. They may differ in conditions of detention:
- temperature condition;
- salinity of water;
- the presence of different plants;
- way of movement and life (bottom or pelagic).
It is important to take into account the fact that sharks of different sizes feel uncomfortable in one aquarium.
There is also a different diet. Although all decorative shark fish are famous for their excellent appetite, there are still some differences:
- time frame for eating (morning-evening, day, or only at night);
- the presence of fasting days, which are fraught with "trouble" for smaller residents;
- varieties of food.
And most importantly - the neighborhood with other inhabitants. You can’t settle with these predatory fish small fish, they can at some time “pass for food” for hungry hooligans.
Other fish should at least not be inferior in size to their predatory neighbors, and not be too "shy."
If all this knowledge has not stopped you and the desire to acquire a home shark is still left - you will become the owner of the most unusual and exciting indoor pond.
