Bamboo filter shrimp inhabit Indo-Pacific and Malaysia. They live in calm and slow rivers, where they catch small pieces of food. Usually they live in numerous groups. The calm and peaceful nature of the shrimp allows it to settle in the home aquarium next to other small neighbors.
The filter shrimp (banana) in the aquarium will be pleased with the stones, bark and pump, which will give a favorite current to the creatures. Asian individuals are very fond of rapid flows of water. With their transparent and fluffy fans, they filter algae, feed, microorganisms.
The color of the shrimp cover (the photos are given in the article) can vary quite strongly from red, brown to sand, green, yellow shades, sometimes with the appearance of a white strip on the back. Coloring depends on habitat conditions, molting, food and the environment. Shrimps are well developed mimicry, they are like chameleons, they know how to change their color.
It’s impossible to know in advance or foresee how they will behave in a new aquarium. There is evidence that the fan shrimp has a brighter color in hard water, but this data is not confirmed.
The front pair of limbs of these creatures turned into a kind of fan, with their help, food is filtered from the water. If the food in the water is not enough, the shrimp will begin to feed on waste or dead pieces of plants.
Habits of shrimp
Filtration shrimp in the aquarium swim quite well, both forward and backward. Usually they move forward with their heads, but sometimes they begin to back off sharply in extreme conditions. They can not be called bottom creatures. They calmly master absolutely all the space of the aquarium, take places near the surface of the water, on the snags. But at the same time they prefer places with a strong current. As soon as the flow of water weakens, the shrimp (photo below) instantly go in search of a new turbulent source. Sometimes they succeed in the most extraordinary tricks that they can do when they run out of an aquarium. Therefore, it is advisable to close the container with shrimp.
Features of the structure of the body
Filter shrimp in the literature often has another name – fan. This is due to the fact that the front pair of its limbs transformed into something like a fan or panicles, with their help this creature feeds. In crayfish, for example, the forelimbs are modified into claws, while in the banana shrimp, the fourth and fifth thoracic segments are pubescent. Each fan consists of hemispheres formed by dense rows of bristles. It should be noted that this is not the simplest structure of the claw, but so convenient that the food just floats in your hands. The only thing that is required from the shrimp is to choose a place more comfortably – so that there is a good flow.
In the water there are a lot of suspended particles, which somewhere settle with time. However, how to collect such food? Claws are very inconvenient in this case. But the limbs modified in the fans are very good. It should be noted that the filter shrimp can wield them with great skill and incredible speed.
If streams of water carry enough food, then little creatures do not need to strain at all. Food itself falls into the trap. That is why shrimps in an aquarium and in reservoirs are located upstream and open their limbs. The fans themselves are gradually filled with food. Periodically, they slam shut, it says that the food gets into the mouth to the shrimp. Moreover, this mechanism is so well developed that while the food from one fan enters the mouth, the other is open at the same time and continues to catch. The principle of priority works in order not to waste time.
Filter shrimp is an awkward creature. Fans are very convenient for power, but they create considerable resistance when moving. Therefore, in order to constantly resist the flow of water, you need to have sufficient for this body weight. In addition, another pair of limbs they have turned into a powerful "cling". With their help, shrimps are kept on algae, snags, and at the same time they are not demolished by strong streams of water.
As a result, they have only two pairs of legs for walking. This is completely inconvenient for those body sizes that shrimps have. Therefore, they are so clumsy. However, the creatures themselves are not at all worried, they are perfectly adapted to life.
Appearance of atiopsis
Atiopsis can reach nine centimeters in length. Males have more developed walking limbs, but they use them more likely as hooks to hold onto plants, rather than for walking. In addition, with their help, they loosen the ground in search of food.
The color of shrimp belonging to different populations can vary greatly. Color depends not only on the diet, but also on the mood of the creature. After molting, atiopsis becomes much brighter. And the color of the shrimp in the aquarium also depends on the soil, and on the scenery. As a rule, they have a light brown color, but reddish individuals are also found.
Shrimp-filter feeders, the content of which at home is not particularly complex, can be safely settled even with the largest representatives of the aquarium world. There is hardly a fish willing to offend them.
As for the breeding of shrimp-filter feeders at home, there is no information about successful attempts. The fact is that females carry several hundred eggs about twenty-two days. Then floating larvae emerge from them, which either die during molting or are successfully eaten by parents, if they are not transplanted to a different container in time. However, there is an opinion that they can successfully develop only in brackish or sea water, apparently, they need some kind of specific food. Therefore, we can conclude that all the shrimps on sale are real “savages” who were caught and brought to us for aquarists.
Under the conditions of an aquarium, shrimp must be fed up, because here the water is not enriched with plankton. This is best done by spraying the mixture or dry feed in the course. You can also use small frozen moth for feeding.
In general, it is good for a shrimp when there is some kind of mist in the water, in a perfectly clean aquarium it will certainly starve. As observations show, even with two meals in these conditions, these creatures do not live long. Apparently, they do not have enough of such nutrition. But in a slightly muddy water, they feel much better. Here there is a dilemma: whether to choose clean water for fish, or with admixtures – for shrimp.
In general, for these creatures it is extremely important to constantly catch at least something in the water. Even just filtered clay particles will contribute to the development of shrimp cover. Sometimes aquarists are advised to add chalk to the water, because there is always a shortage of calcium salts. The rest of the shrimp do not require special care. The temperature regime for them should not be below 24 degrees. Increasing it in the summer to thirty degrees shrimp tolerate absolutely calm.
Shrimps often change their color. After molting, sometimes they turn red, and then quickly brighten, and then, in mood, they change shades from light yellow to red and brown. What are the causes of such changes is not known.
Molting in adults is irregular. Sometimes this happens once a month, and sometimes less often, so that algae even appear on the chitinous cover. Interestingly, before the molt the shrimp stops eating, it sits with folded fans or goes to a secluded place. Immediately after changing the shell, the creature becomes very defenseless. It is during this period that if there are males, the females try to fertilize the eggs and set them aside.
These are unusual creatures of shrimp-filter feeders. Before you start such a creature in your tank, think about the fact that it is quite calm, and therefore not very noticeable. So it is unlikely to be an ornament to your collection.
