Ornamental fish are divided into three levels: upper fish, middle fish, and bottom fish. The ornamental fish distributed in three areas perfectly create an ecological chain out. Upper-class fish usually feed on small fish or insects that fall into the water, and even a type of upper-class fish called the "Heath's Stone Carp" can jump out of the water and eat berries that hang on the surface of the water. The "shooting fish" can rely on their unique skills on the surface of the water, spraying out the water column, knocking down the insects above the water surface and eating them. "Silver dragons", or some fish of the family of fish, will also jump out of the water to hunt.
Meso-pelagic fish feed mainly on small fish. Horse mouth is actually a typical carnivorous mid-level fish, and lua-playing aquarists can generally fish in the rapids, and it feeds on insects, including other fish that can be swallowed by the mouth. There are many typical middle-class fish, and the common lamp fish is actually a middle-class fish, which has strong reproductive ability and is usually caught by other middle-class fish. One eyebrow Daoren, black tail big hook, are very representative of the middle fish.
The family of benthic fish is actually no smaller than that of upper-middle-class fish. The species of benthic fish are extremely numerous. Benthic fish generally have a characteristic: poor vision. Catfish in the catfish family basically rely on their antennae for food. It can be said that the fish living on the bottom actually have the same effect as the "cleaning workers". They are at the bottom of the food chain. To say that it is ugly is to pick up others and eat the leftovers. In the fish tank, it has the effect of cleaning up food scraps. Benthic fish, good and bad, how to choose the right benthic fish? First of all, the tank of small fish should avoid catfish, fish that can eat fish such as catfish.

The grass tank recommends that you choose some small special-shaped fish. The golden beard is actually a very good choice. And the golden beard can play an excellent role in algae removal, avoiding algae from affecting the growth of aquatic plants. Moreover, the golden beard does not turn the sand like the loach, and there are not many bad habits of the golden moss rat. Its golden beard role, very suitable for raising in the grass tank, will not pose any harm or threat to other small ornamental fish in the grass tank, safety, and the removal of food debris and algae removal effect are excellent.
The mouthparts of ratfish are longer than those of heterotypic fish. If you plant a ground-crawling dwarf pearl in the tank, the xenomorph fish may not be able to achieve too good results. The slender mouthpiece of the ratfish can reach into the aquatic weeds and clean up the impurities at the bottom. Ratfish are still very friendly to small fish. However, it must not be kept together with carnivorous fish, and when the ratfish is in distress, it will bounce off the spikes on the back, easily stuck in the throat of the carnivorous fish, and finally cause the death of both parties. Paired with small fish, ratfish and golden beards are actually good. In addition to the golden beard, fish such as the big sail are also no problem.

There are actually more benthic fish that can be raised in South American tanks. South America itself is also home to benthic fish. There are basically no aquatic plants in the place of origin, and most of them are sunken wood. And most of the water quality is slightly acidic. The South American tank is capable of raising some of the larger fish. For example, the earthbream.
Soil seabream filter sand is very effective, but it does not remove algae. If you raise the earthbream in a grass tank, it will pull up all the aquatic grass. But this will not happen in the South American tank. The water quality of the South American tank is very suitable for feeding soil seabream, and the fine bottom sand is also conducive to eating soil seabream filter sand in addition to better landscaping.
If your tank lights are dimmed or whatever, in addition to other xenomorphic fish to choose from, in fact, Crown Helicopter is also a good benthic fish. Crown Helicopters especially likes to live in environments with a lot of sunken wood. The first is because the tannic acid released by the sunken wood can create and raise the water quality of the Crown helicopter, and the second is because the Crown helicopter itself is mimetic, looks like a tree branch, can be camouflaged in the sunken wood, can increase its sense of security, and the hair color state will be better. Crown Helicopter is very diligent in removing algae, and it is highly productive and easy to reproduce.

In addition, the ratfish we just mentioned are also very suitable for raising in South American tanks.

Benthic fish native to China, with the exception of gobies, are basically loaches. Yes, the main protagonists of the benthic fish in the native tank are various loaches.
Personally, I am relatively fond of loach. The mouthparts of the loach are similar to those of the ratfish, and can be fed into the sand for filter feeding. The effect is similar to that of a ratfish. And this stuff is very good to raise. It's also pretty good after the hair color.
Beautiful little loach is no problem. Beautiful loach I personally feel that the appearance value will be higher than the loach, its color is also more vivid, better than the loach. The beautiful loach is mainly scavenging, and in the wild it is responsible for eating the fish that sink to the bottom after death. It is still useful for cleaning fish tanks, and is better to use than non-scavenger fish.
Why is it not recommended to use the drum-cheeked loach here? Although previous articles said that this thing is very good to raise, but it is a real carnivorous fish, I know that I have some regrets after raising it. Here we recommend that you choose: flower loach, beautiful small loach, or small swim bream.
If there are no benthic fish in the tank, the bottom needs to be pumped once a week. Raising a few benthic fish is indeed more convenient, which is an indispensable part of the ecological chain.
If you also like to raise ornamental fish, you may wish to start pointing out a point of attention, all you need to know about fish farming is here.
