I believe that there are many aquarists have to raise native fish, no matter what fish tank is easy to grow green algae or a lot of food residue fell to the bottom of the fish tank piled up, there is no organism to clean up these green algae and food residues, but feel that there are very few native fish can be used as tool fish, this issue to introduce several and good-looking and practical tool fish.
<h1>Vegetarian - sucker</h1>
Loach can be seen in many native fish tanks, sucker loach in the wild environment are living in some water bodies with fast flow speed and low water temperature, so sucking loach is very suitable for polyculture with some rapids fish, such as: shrimp tiger, pomfret, striped small fish and other small and medium-sized fish polyculture, but with the albacore, horse mouth and other carnivorous stream fish is easy to be eaten. Its ability to clear algae can be said to be "great", and a moss-covered stone is enough to clear it in a day or so. And the breeds of sucking loach also have a lot of hair color is also very beautiful, but in their fight with the same kind of food and territory, sucker adult males will grow "star chasing" on the lips (star chasing is similar to antlers, used in mating, fighting).
They will push each other on the stones, so it is not enough for them to raise some moss from the stones alone, so we can feed them with some vegetarian patch feed, and they will also clean up the food scraps left over from other fish. Loach is not suitable for polyculture with tropical fish, because it lives in the wild in some places with low water temperatures, so it is best not to raise them at a water temperature of more than 28 ° C If it is higher than 30 ° C, it is very dangerous, and if the water temperature is too high, it is easy to die.
<h1>Mobile degreaser - medaka</h1>
Tropical fish in the most famous oil film is definitely the Mary fish, but the Mary fish put in the original style of the fish tank is out of place, but in the original family there is also a degreasing film sharp tool that is the medaka, the mouth shape of the medaka is similar to the mouth shape of the Mary fish and the medaka is also an upper fish, it can be said that the appearance is not the same but the function is still the same, the ability of the medaka to clear the oil film is not bad, and its adaptability is better than the Mary fish, the only drawback is that it can not be mixed with too large fish Because the medaka is a fish species that everyone can bully, it is too weak.
Medaka in the water temperature requirements are not large, now there are many back medaka has been developed, the color of the back of the medaka will not be worse than a variety of metallic colors have also been developed, its degree of ornamentation will not be lower than mary fish, the ability to work is also comparable to mary fish, but also very suitable for novice aquaters to raise.
<h1>Pigs in the water -</h1> salmon
Salmon can be said to be no different from pigs, as long as it can be eaten will not let go of what food residue, and the hair color of the salmon is also very good, he can be polycultured with a lot of fish and longfin carp, horse mouth and other ferocious fish polyculture is also OK, and shrimp tigers, suckers and other milder fish together with the polyculture is no problem, it is also very receptive in water temperature, but the temperature is best not higher than 30 ° C, because the temperature receptivity is also temperate fish, so the temperate zone is still not too high.
Although there are many varieties of the sturgeon but a variety is best not to buy, that is, the volcanic sturgeon produced in Chongqing is also called the southwest sturgeon, because the geographical distribution of the volcanic sturgeon is very narrow, and the ability to grab food is stronger than other sturgeon, so it can not be released in other waters other waters otherwise it is easy to lead to ecological chaos, because the geographical distribution of the volcanic sturgeon is narrow, so its population is also very small, and it has not been artificially bred in large quantities, so at present, a lot of volcanic sturgeon sold in the aquarium market is wild fish, we have to protect it, Refuse to buy them, anyway, other sturgeon hair color will not be bad, such as: high body sturgeon, Qi's trout, Chinese trout to raise the hair color is not worse than the southwest sturgeon, novice aquarists recommend raising high-body trout, high body trout can be said to be the most solid skin.
